64-bit Windows manifest files

[jorgon]

It is crucial that you say 'processorArchitecture="*"' in the manifest file. If you mention ''processorArchitecture="x86"', your application will not be able to launch in 64 bit Windows.

Strangely, the "assemblyIdentity" type must remain as ="win32".  If you specify "win64" or "*" it doesn't work.

I also found it strange that the 64bit libs are still all something32.lib, e.g. user32.lib.

P.S. Microsoft seems to use processorArchitecture="amd64" in their own manifest files, I had to open up one of their progs to find this out beause the only official documentation I could find was refeering to Itanium 64bit apps. See this thread.
