I want to make sure that on 64-bit Windows, 32-bit application can be installed/run without any issues? And it is guaranteed by Windows backward compatibility?
For example, any application (e.g. Microsoft Windows Media Encoder 9) which runs smoothly on 32-bit Windows 7 can run smoothly on 64-bit Windows 7.
I am developing some software and actually my question is whether release x86 version is ok for both 32-bit and 64-bit Windows 7. If WOW could guarantee it, it could save my work to package different binaries for different platforms.
