I have a really old installer (legacy app) that we are trying to get running on a Windows 7 64 bit os.
Previously it has only been installed on Windows XP 32 bit. I get the following error when I try to run it:
The version of this file is not compatible with the version of Windows you're running. Check your computer's system information to see whether you need an x86 (32-bit) or x64 (64-bit) version of the program, and then contact the software publisher.
Contacting the software publisher is not an option (software is super old).
Is there a way to get this to work? Some sort of compatibility mode?
The only thing I have heard of that will work is a Virtual XP on the Win 7 box. The problem is that this software is a part of a whole software set. I would have to put all of the pieces on the Virtual XP or none at all.
Before I go down the road of putting it all on the virtual xp I would like to know that there is no way to get it all on the Win 7 os.

You say it is a really old installer, is it a 16-bit application? All 16-bit application support was dropped from Windows 7 x64 - It will not run, at all. You will need to use an emulator or move back to 32-bit Windows. XP mode in Windows 7 might be an easy solution to get this application up and running seamlessly.
