Yes I have Windows 7 32 bit not 64 bit. And I also have Windows 8 Consumer Preview 32 bit. And WMP 11 for Windows 7 works on Windows 7 32bit and Windows 8 32 bit.

Also WMP 5.1,Mplay32 from Windows XP also works on Windows 7,Windows 8 and Windows Vista. You just copy the Mplay32 exe from Windows System32 on Windows XP onto Windows 7,Windows 8 and Windows Vista. Then place the Mplay32 file in Windows/System32 on Windows 7,Windows 8 and Windows Vista.

So as well as having WMP11 which is working on Windows 7 and Windows 8,I also have WMP 5.1 or Mplay32, as it is called on Windows 7 and Windows 8. And also on Windows Vista. And it runs alongside WMP on all 3 versions of Windows, the same way it does on Windows XP.

So WMP 5.1,Mplay32 from Windows XP also works on Windows 7,Windows Vista and Windows 8. But WMP 6.4,Mplayer 2 from Windows XP,however does not. WMP 6.4 only works on Windows XP.

I never buy 64 bit Windows 7 as I think it is slow and it is also not compatible with 32 bit Windows XP software. If you did a custom install of Windows 7 from the full install CD you should also have the 32 bit Windows 7 CD.

Could you not install the 32bit version of Windows 7? That would be better for you if you want to install and run your software from Windows XP and Windows Vista.As most Windows XP and Vista operating systems are 32 bit. Andrea Borman.
