I am running into this issue:
warning : Platform 'x64' referenced in the project file 'xyz' cannot be found. Please make sure you have it installed under '%VCTargetsPath%\Platforms\x64'.
I had tried the same project/solution and it ran just fine in another computer that also had windows 7 64 bit, but a full version Visual Studio 2010 64 bit.
Now on this other computer, I'm trying to run the same program with Visual C++ 2010 express but get that error. What's more, my solution is, by default set on the configuration manager to x64, not win32. However, I can't open the project properties unless it's set to win32, otherwise it says "unknown error" on a pop up error message. Any idea is to be done? Anything I could add?
