I am getting a "Not a valid Win32 application" error message when attempting to execute an .EXE downloaded from Microsoft on Windows XP, but it executes fine on Windows 7.

What could be the problem?

Which application? – VenkatH Oct 14 '12 at 5:58

It sounds like it's probably a 64-bit app you're trying to run on a 32-bit machine.

Some win32 exe's coded for Windows 7 will not run in XP with the same error message, we need to know what they downloaded to know for sure. – Moab Oct 14 '12 at 16:41
