I have windows 7 64bit .exe file but whenever i try to install it in windows xp 32 bit will say ( Is not a win 32 valid program)
What is this windows 7 64bit .exe ?
Is that windows 7 64bit installation media? Are you trying to install windows 7 64bit on your windows xp computer?
If so, then you have to boot from windows installation media, to install windows.
If that windows 7 64bit .exe is some software installation, then you can't install it in 32bit windows.
