Windows 7 64-bit: Running 32-bit Applications

Written on January 13, 2011 by William George

Windows 7 has taken root in the PC community over the last year, a great improvement from the little-liked Windows Vista, and we've made the 64-bit version the de facto standard on the computers we sell - to the point where we no longer even list the 32-bit version on our website. We can special-order it still, though, and I find that I am often asked by customers if they would be better off with that because they need to run older programs. This makes me think there may be some misunderstandings about 64-bit Windows out there, so let me set the record straight.

The last three editions of Windows - XP, Vista, and 7 - have all been available in both 32 and 64-bit versions. XP 64-bit was only rarely used, though, as it was the first step toward 64-bit computing that Microsoft took... and driver support was never very good, resulting in the vast majority of our customers from that era sticking with 32-bit. As memory (RAM) has become cheaper and more plentiful over the years, though, the ~4GB limit in 32-bit operating systems quickly became a sticking point, and thus when Vista debuted the 64-bit version was installed on a substantial amount of the computers we sold. That trend has only continued with Windows 7, and while that is the OS of choice for Windows users these days there is no problem running most older, 32-bit applications.

This is because Microsoft understands the importance of the backward-compatibility which has always been a hallmark of Windows operating systems, and indeed most programs are still written in 32-bit - either because they have not yet been updated to 64-bit, or because they have no need for the increased memory capacity that 64-bit gives access to. Specifically, a layer of processing was built into 64-bit XP, and has been inheritted by Vista and 7, called WoW64: Windows 32-bit on Windows 64-bit. It emulates much of the software environment 32-bit programs expect, to the point where most older software should work just fine. There are some limitations, unfortunately, but they only affect a small percent of the programs out there; if you want the details on that, you can read more on the Wikipedia page about WoW64.

Still, some folks run into trouble when trying to install or run an older application in Windows 7 64-bit. That can be due to one of the limitations I mentioned above or, more often, related to the added security settings in Windows 7. With XP and earlier versions of Windows, the default user account ran with administrator-level access - and so, therefore, did all programs executed by the user. Increasing online threats have led Microsoft to restrict default user priveledges, though, so older programs that are expecting admin-level access to the system may not function properly.

If you run into a program which doesn't seem to work correctly, and you suspect it may
need admin access, right-click on the icon or shortcut for it and select "Run as administrator". If that fixes things, you can set a program to always run in that mode by right-clicking the icon again and going to Properties, then the Compatibility tab, and checking the box for "Run this program as an administrator".

Another valuable setting on the Compatibility tab is the Compatibility Mode option. When a program runs, the operating system is able to tell it what edition of Windows it is running on. Unfortunately, some programs try to be smart and look at that before starting up - and if the version of Windows they are told is not one that the software expects it may simply say it cannot run. I've also seen that happen when going to install a program, and when it happens it can be quite annoying. The way to work around this is to have Windows claim to be a different version - to lie to the program, in effect. That can be accomplished by selecting an older operating system from the Compatibility Mode drop-down menu, again in the Properties for an icon, shortcut, or program. If you are running into this when trying to install software, you will need to track down the executable which is trying to run and right-clicking on it to change this setting. You may also need to try a few different Windows version settings, to find one that the software accepts.

Lastly, if neither of the above helps, you can run a different version of Windows - whatever one your software needs - from within a Virtual Machine.  That is a type of program that lets you run one operating system within another - a great tool for testing different OSes, or even isolating certain types of work (like visiting suspicious websites) from the rest of your computer.  For the purpose of running older software, having a virtual machine of Windows XP would give a lot more flexibility in terms of running programs with specilized needs.  Knowing that, Microsoft actually provides a streamlined solution to give their customers just that: XP Mode.  It is a free download for anyone with Windows 7 Professional or Ultimate (but not the Home editions) and, for those of our customers who know they need it, we can often pre-install it when building a computer.

I am planning to buy a Lenovo Thinkpad with 64 bit Win 7 Pro installed. Lenovo will include XP mode in the build. Am I correct that my 32 bit programs from my current XP computer will work on the new computer?

Ken -

I believe the article actually answers your question already, but to reiterate: Windows 7 will run most 32-bit applications just fine. If you do have some programs that give you trouble, though, XP Mode is indeed a good approach to solving that problem.

As a side note, we are able to install XP Mode for customers who request it (assuming they purchased a version of Windows which enables it). Even if we don't, though, it can be easily downloaded later on.

Hello @William, Thank you in advance you're most helpful by all means and I am currently testing that theory in 2017: About how windows-7 will run most 32 bit applications with 64 bit laptop or 64 bit desktop. Because of the strong hold that Google has on the web and it's constant changing bs that never properly works, and the lack of concern from adobe, java and a few others that don't intend or refuse too give support following "Microsoft"- from the beginning and on going,, even windows defender is blocked from administrator access for "enabling" change or modify because it's killed by policy among other programs old and new. Further more no one with in big companies cares, so nothing has been resolved to fix anything. Truthfully with all honesty I hate and despise windows and companies that neglect people and the users needs.

This is the exact information I've been scouring the internet for! Thanks! I'm soon to leave my beloved XP and get a Win 7 laptop. There are two "old" programs I use constantly and can't live without, Microsoft Picture it (photos) and Adobe Audition 1.5 (audio). Windows Pro, with virtual XP should do the trick. (I hope!)

Posted on 2011-04-26 00:08:40

Just making the switch from XP to Windows 7 and having BIG problems getting
my Adobe Audition program to work...even in XP mode. I think both Microsoft
and the Adobe folks are to blame. Why does it have to be sooo hard ?

I'm wondering about apps with ODBC connections to a database that were built when the ODBC drivers were 32 bit.
I already have Win7 Pro and I am using the 32 bit ODBC administrator to set up a DSN for the database for the app.
The app works this way, but since you say most 32 bit apps should run in the 64 bit environment, I am wondering if the app could run under the default 64 ODBC administrator. (as it is, is can't run on Win7 Home edition.) If not, it would mean that a LOT of 32 apps out there cannot run in Win7 Home version etc. ODBC is still used very widely, particularly in the business world where ODBC has a large legacy of installations.

Posted on 2011-06-30 16:13:31

@BC -

I'm not personally familiar with ODBC, but a quick Google search indicates that 64-bit Windows has both 32- and 64-bit versions of that interface built-in. See the following link as evidence: http://support.microsoft.co...

Can I revert from WIN 7 64 bit to 32 bit?

Posted on 2011-07-20 22:04:43

@Ethan - Unfortunately no, there is no mechanism for moving from 64-bit to 32-bit (or the other way around). They are completely differed under the hood in terms of the way they are built, so the only want to switch is a completely fresh installation... in the process wiping out your programs and any data on the C: drive.

I've had quite an issue with Copier drivers using Windows 7 Ultimate; I load the 64 bit drivers, set up the printer/copier using a local TCP/IP port, no sharing, and . . .nothing. The PC sees and communicates with the Copier, but attempting to send any print jobs to it simply deposits them in the ether - they never show up in the queue of the copier itself.

HP printers I've had no problem with, its the Lanier/Ricoh series copiers that are giving me grief. Any suggestions would be welcome.

Posted on 2011-07-22 15:39:23

@Michael - For specific situations like that I would recommend contacting tech support for the copier companies. I used to work in a copy shop with a digital computer->copier hookup, and I remember it being a lot more complex to set up than a printer. There may simply be some option on the copier side that needs to be set, or something in the driver options... but I'd expect the manufacturer's tech support to be able to help with that. Good luck!

I purchased a  64 bit Windows 7 machine and lost ALL my beloved pheriferal equipment - a very expensive Epson Laser Printer, an Epson flatbed scanner, an external floppy drive and a very nice Canon photo printer.  I only had drivers for 32 bit.   I contacted the on line help to manufacturers and looked at Microsoft for drivers, too.  Nothing was out there that would work for any of them and NO ONE seemed to be interested in my problem. 
I have hundreds of dollars tied up in them.  Now they are collecting dust because neither the manufacturer nor Microsoft can give us drivers to make them work although all of them work perfectly.  Why can't we get more support on drivers for these older pieces of equipment?  It is rediculous to throw equipment in the dump that is perfectly good.  I can't afford all this either.  If we are bound to have to go to Windows 7 with everything, (You cannot find a machine anywhere around here that does not come with Windows 7 and 64 bit)  supply us with all the drivers to match!!!

Posted on 2011-11-27 21:30:37

I think it is just a matter of the cost of the manufacturers to support both sets of drivers, at double the cost.  When $15 of memory will overwhelm the support of a 32bit operating system, I just don't see much life left there.  It is definitely unfortunate that they aren't supporting their existing customers though.

One thing you could do, though, is use VirtualBox to install Windows XP as a virtual machine, then use your older USB devices from there.

It is done for purpose to force people to spend money on new technology. They got their profit, so from their perception why should they care. For you it is an expensive lesson that whatever you buy has only limited time and it is vital to save all your drivers as soon as you get new equipment and store it in safe location.

Posted on 2011-12-25 17:38:49

What? That made no sense. Storing drivers from another operating system is not going to help him in this scenario.

The other option is for you to master pc language. Most drivers were written in Assembly. Then go and create your own drivers.

my new laptop came with 64-bit win 7. my engineering softwares that worked fine in XP & Vista didnt even install upgraded to win 7 home premium 64- Bit still no help. I downgraded to 32 -Bit but still same problem so upgraded to win 7 home premium 32 bit but same issue. then i downloaded a pirated copy of win 7 home premium 32 bit from internet and all my softwares work fine and i dont understand this phenomena and it makes me mad on microsoft.

Does any one know what could make some 32 bit windows not able to install and some having no problem with it.

Using pirated software is extremely dangerous. Current software is very complex, requires team of programmers and extensive testing. You might be able to use pirating for experimenting, never for complex business use mainly on expensive equipment. Once connected to internet your action is automatically recorded to systems. Plus you want to be sure that you know exactly what you are doing. Otherwise it can ruin your system for ex. by attacking pointers, in better case, in worse get high fine and rockhouse accommodation.

I have a "legacy" mission critical database application that runs fine under XP 32. However our office computer is getting a little dodgy so I think it's time to move on. I tried this app before under Vista and it crashed. It needed to be able to write to file on the root drive and Vista fought this. I managed some workarounds but the app was never totally stable so I gave up and stuck with XP. I'm building a completley new system, latest and greatest everything and I'd like to go Windows 7 64 bit to take full advantage of the OS and the hardware. I know I can try a dual boot scenario but I was wondering how compliant the XP Mode would be. Would it allow the app to write to the root drive as needed or would it crash too? The app will never be updated I'm sure and a replacement app is thousand$. Ideas? Thanks.

XP Mode is comprised of a whole copy of Windows XP Pro virtualized within Windows 7.  It is sort of hard to explain fully if you have never worked with a virtualized OS before, but in effect that means that XP Mode - and any programs running in it - have their own "root drive"... or at least they think they do.  And yes, they have full permission to write to it.  However, it is not the true root drive of the whole computer, as XP Mode does not 'know' it is running inside a bigger OS.  I'm not sure that made much sense, but I think you will see what I mean once you try it.

Also, just a thought: it sounds like your application may have simply needed admin level access for what it wanted to do.  Did you try the solution recommended above, regarding running it as an administrator?  If not, I would try that even before setting up XP Mode.

Windows 7 won't run web-based app as it's looking for 32-bit version.  Anything I can do to fool the website to think I'm running 32-bit system?
Thank you for your support.  I read where I'd need to reinstall the 32-bit version and lose everything, but I was hoping I could fool it.

Posted on 2012-01-09 23:11:22

As far as I am aware, a website should not be able to tell (nor should it care) what version of Windows you are running.  Now perhaps a more complex application in a website could, but I'm not sure how one would deal with that - so lets take the more likely case instead.

What I suspect may be going on is that you are using a 64-bit web browser.  Windows 7 64-bit comes equipped with two versions of Internet Explorer: one 32-bit, and one 64-bit. If you are using the 64-bit one then it is certainly possible that some websites would not work; for example, up until recently Adobe's Flash environment was not compatible with 64-bit browsers.

If you open the start menu in Windows 7 and type Internet Explorer in the search bar, you should get several results.  Try running the one simply called "Internet Explorere" (not the one ending in "64-bit") and see if your web app works that way.  Good luck!

I have Win 7 Starter and need to run it in 64 bit mode because I want better sound quality (my laptop is used as a music server for music streaming through a USB/DAC).  How do I go about changing the 32 bit mode to 64 bit mode in my laptop?  I'm assuming my laptop is running a 32 bit mode, but how can I make sure?

Posted on 2012-01-30 13:35:31

You would have to completely re-install your OS using a disk with the 64-bit version.  I don't expect moving to 64-bit will have any effect on sound quality.

We are a small training company that sells a software tool for creating a Task Analysis, the first part of our ISD approach. Due to the recession, we barely have any clients. But one of these clients who has been using our software and ISD process for many year, just wrote to say they are converting all their computers to Win7 and they can't open our software in that OS. I've read the info about using virtual WinXP, which appears to be a good solution, but is there a way to add a quick fix to the application itself so this issue won't even arise. We developed the application originally in 1992, made major upgrades to it in 2002 to meet the needs of clients converting to WinXP. Now, 10 years later, we don't have the money to pay for another overhaul. Any suggestions?

Hi, Guru Omega. I developed in the past a couple of assembler programs for the OS that was then in force (Win 98) and worked superfast and reliable. I enjoyed developing those programs.
Then came Win XP (a super good OS) but ports were not accessible. So, my programs didn´t work. Now has come Win 7 in 3 and 64 bits, and of course the manufacturers have made new changes deleting parallel port. The manufacturers and software developers don't care at all about users. They think solely in themselves. People will then need new drivers, cables, software, utilities and so on. This is a kind of dictatorship.

Now installed win7 Pro 32 bit, but its taking too much RAM & CPU 100%, Checked for any viruses, But no viruses and formatted again & installed Win7 64bit Pro version. But still same problem
Pl help me how to solve this issue

I have tried every trick and hack in the book to get my GPS software to install .. running in compatibility mode, as admin etc etc ... still when I try to install using the .INF file included in the software Windoze 7 complains that there is not compatible driver  yet it is the same driver I used in XP... and furthermore it tells me to make sur there is a COMPATIBLE 64 bit version of my driver... so it appears that win 7 IS NOT  backwards compatible with 32 bit software ... so how do I force windoze 7 to accept this 32 bit software that runs perfectly on win XP? the GPS program im trying to use is a navman e series gps ... from rend macnally and b4 anyone says to check with them they dont even support that product anymore... yet the drivers as listed under XP are made by a company called talon gps.. cannot find anytihng in an internet search on them. I do not want to have to load up my computer with a virtual machine to use my equipment but what other choice do I have...?

I've bought Sony VAIO laptop and installed 32bit Window 7 OS cause I didn't have 64bit one. Everything seems ok except network connection. I couldn't find network adapter and drivers. It's causing a lot problem. There's no LAN and adapter at all. What should I do in that case? plz help me

Posted on 2012-09-15 05:08:35

I would recommend using another computer to find and download the right drivers.  Sony should have them somewhere on their website, and if you download them to a flash drive or burn them to a CD and then move them over to the laptop you should be able to get the network connection on the laptop itself up and going.

 To be honest I'm very disappointed about the 64 bit system. My old computer is 6 years old no problems with for instance photodex. Now I bought a super computer 2011 socket I7, 8 cores and 32 gig ram, now suddenly my computer runs out of memory with for instance Photodex. My pagefile is 30 gig large, anyone have a solution?

Posted on 2012-09-20 11:37:30

Photodex itself is not a 64-bit program, so it should be limited to only using 2-3GB of your memory (though having more than that can still be very beneficial for other programs).  When you say your system is running out of memory, can you describe what is telling you that? (is it a pop-up error, or are you watching the memory usage graph in Task Manager, etc)

As for the pagefile, I've never liked how Windows makes that larger the more memory you have; I simply turn mine off on systems with decent amounts of RAM, but if you really are somehow using all of your RAM then you don't want to disable the pagefile.

My Civilation II cd willnot load on my new 64 bit Windows 7 Toshiba. It claims to be not compatible.

Posted on 2012-09-29 21:48:03

Have you tried the suggestion in the blog post above about running the installer in compatibility mode?  If not, put the CD in the drive, cancel the autoplay that tries to come up, open Windows Explorer, navigate to a view of the files on the CD, find the one that is the installer (often something like 'setup.exe'), right click on it, go to Properties, and set both of the following options:
- Run as administrator
- Run in compatibility mode for Windows XP (or 98, if it was released before XP)Once those settings are saved, double-click on the program and see if it installs okay.

Posted on 2012-10-07 23:02:22

If you have tried everything here and it hasn't helped, then you may be up against a program that simply won't work.  Really, though, almost everything should work inside XP Mode (unless it needs heavy 3D).

Your links appear to relate to running applications that are available as either 32- or 64-bit in a forced 32-bit mode, inside of 64-bit Windows. If that is what the original poster meant to ask about then you are correct, but I took his question to mean "how can I run 64-bit programs in a 32-bit version of Windows"... which is impossible.

I have been given software on a CD written in XP that I've seen run on Windows 7 32 (whiich I do not have) bit but the disc looks blank on Win 7 64 bit pro even in an XP virtual machine! Help?

Posted on 2013-03-07 16:08:22

I don't think that has anything to do with the version of Windows. It sounds to me like one of two things:

1) The CD was not finished. There are a couple ways of writing data to CDs, and one of them is designed so that data can be added over time. That works great with a single computer, as you can add more and more until you are finished - but you can't access the data from another computer until you do complete the process. That is called 'mastering' the disc usually, and if that wasn't done on the computer where the CD was burned it will appear blank on any other computers (regardless of operating system).

2) The CD itself isn't compatible with the drive on your computer. This is more rare, but I have definitely seen times that a certain brand of writable discs won't seem to work with a given CD drive. If the first issue is found not to be the case, try the disc in a third computer to see if its visible there or not.

sir what r the effects if we use 32bits instead of 64bits in ultimate i mean promblems like difference in clarity or screen resolution variying etc could u state us sir

Posted on 2013-09-24 15:25:23

There would be no visual difference like that. If you are talking about using a 32-bit version of Windows, then the major effects are that you are limited to using <4GB of memory and you cannot run any 64-bit applications. If you are talking about running 32-bit programs inside of a 64-bit version of Windows, then those applications are limited on how much memory they can access (2-3GB, depending on how they are coded - even if the system has more). Aside from that, though, they should work fine.

As the article above talks about, you should be able to run most 32-bit programs without a problem even under 64-bit Windows 7. If you run into trouble, try the various methods described above to resolve it.

Hi I have Windows 7 home premium and wanted to use my works auto-cad I have been told that my system is 64bit and the auto-cad software is 32bit and there is no way they will work together, is there anything i can do?

Posted on 2013-10-14 19:21:26

You could try the several approaches described in the article above, as there shouldn't be a problem getting 32-bit software running in a 64-bit version of Windows.

However, there may be bigger issues: specifically, licensing. Major industry programs like AutoCAD tend to have strict licensing terms about where it can be installed - so unless you work is paying for an additional license it might be bordering on piracy (at least from the perspective of the software makers). Definitely take care to check that out before even trying to install it.

How do I know if Win7 is running in any form of xp? I am thinking I don't want to use any form of XP with XP support ending in April. I do not have xp mode or virtual machine and when I right click the 123 icon I can see it is not running in XP compatibiloity . I have Lotus Smartsuite using 123. When I start 123 the screen blinks then loads. same when closing. There is some minor changes with the screen display. Could this just be 32 bit 123 running on Win7 64 bit home premium? Should I be concerned with Smartsuite and XP support ending?

I am running the 64 bit version of Windows 7 and it won't let me run my old Dos programs. They will run ok on the 32 bit version of Windows 7. Is there any way to make them run on the 64 bit machine?

DOS programs are 16-bit, so those will not run natively in any 64-bit version of Windows. You can try using the Windows XP Mode described in the article above, if you have Windows 7 Pro, or you could give DOSBox a shot: http://www.dosbox.com/

Thank you for responding to my question so quickly. I only have Windows 7 Home Addition on this computer. Is there a chance that Virtual Machine would work for me, and can I even get it for this operating system?. I have tried DosBox, but it doesn't support my printer.

Hmm, using a virtual machine might work... but it can be tricky to get printers to pass through that. It would be worth a shot, though, if you have a license of Windows XP available. I would recommend using VirtualBox, since that is a free virtual machine host. Good luck!

i just installed office 13 which happens to be a 32 bit programme on my desktop (64 bit computer)....and so i was just wondering, will the office 13 i just installed be giving me problems when using?

You should be just fine! The normal / default installations of Microsoft Office are still 32-bit, even in the latest version, but as mentioned in the article above that works just fine for most applications (Office included) in a 64-bit version of Windows.

Hello, I have a program installed, it's 32-bit. My computer is 64-bit, Windows 8. It doesn't open correctly, but in the Task Manager it says it is running, but I don't see any windows. I tried Alt + Tab, I tried your XP mode, and all that stuff, but can't do it. Is there any application/software that allows me to run my PC as 32-bit or similar?

It would help to know more about what program it is you are trying to run. The last option, XP Mode (or a similar virtual machine) should *definitely* work - though it is more complex to set up and use. In my experience the combo of running in XP compatibility mode (different from XP Mode) and running as an administrator usually lets most stuff work... but I'm sure there are exceptions.

I have OS Name: Microsoft Windows 7 Home Premium and wanted to run 32 bit application. how can I access 32 bit application without altering 64 bit format?

Posted on 2014-07-26 00:07:29

All of the methods described in the article above should work for Windows 7 Home Premium 64-bit... except for XP Mode, which requires the Professional or Ultimate edition of Windows 7. Have you tried the approaches listed in the article?

Posted on 2014-07-26 00:24:14

This is killing me!!!!! I have changed my program to open as if I am in XP... I have created a Virtual Computer and the darn program is still saying... "The version of this file is not compatible with this version of windows. check your computers information system to see if you need a 32 bit or 64 bit version of the program, and contact the software publisher." Software Publisher says program only comes in 32 bit. WTH do I do now?

Posted on 2015-03-24 21:32:01

Hmm, I would recommend Googling the name of your software program (whatever it is) along with the error message you are getting ("The version of this file is not compatible with this version of windows" - if that is the exact text). I find that looking things up like that can help find if anyone else has run into the same situation, and might help lead you to a solution.
