32bit application in 64bit

Hi Experts,

we have some old programs for 32bit system.
Now we switched to WIN7 64bit.

The old programs are not working anymore but I have to find a way to run these programs.
Do you know a way ?
Is it possible to use a virtual machine in WIN7 ?

did you try in compatiblity mode?

(go to the .exe of your program, properties, compatibility tab, select your old OS)

XP Mode is a 32bit Windows XP Virtual Machine, to allow you to run applications that are not compatible with WIndows 7.

When a 32-bit app won't work on a 64-bit OS, it's typically because the app contains some 16-bit components.  

You may wish to consider something like Citrix XenApp 5 for Windows Server 2003 to run the 32-bit app(s) remotely.

What version of Win7 do you have?  If you have Win7 Professional or above, you can run the XP virtual machine, although you will have to download it and install it.  You get an XP license for it included with W7 Pro.  If you have a lesser version (home premium, etc.) then you cannot run the XP virtual machine.

Windows XP mode is 32bit (or I haven't seen any 64bit version yet), whether you use Windows 7 32 bit or 64bit.

You mean VT support for the CPU? That isn't needed for XP Mode (it was only needed with the first versions of XP mode, but now when you download XP mode you should have, I believe 3 files to download, and one of them is a patch that disables the need for VT mode.

But since you are using a 64bit capable PC it is quite likely your PC has that option.

Also, did you check your application with what the first poster suggested, to change the compatibility mode?

rindiCommented:
If you check the 2nd Link which Hanccocka posted (the second message in the thread), there is a "Download" button in that Link, then you are sent to the download....

Note that applications you run in the XP virtual machine can have icons and be started from Win 7.  It's just that when they start, they will first load the virtual machine, then run the software in it.  It will look somewhat seamless in Win 7, but it will be much slower to load and begin execution than a "normal" app.
