VS2008: No option to convert Win32 C++ project to x64?

I am running VS Team System 2008 on WinXP. I make a new Win32 C++ project (Empty project). I go to Build Configuration to add a configuration for x64.

The only options I have are: - Pocket PC 2003 (ARMV4) - Smartphone 2003 (ARMV4)

I have no option for x64 (or Itanium). However, if I make a C# project within the same solution, I can create and select an x64 option for that project with no issues. But even then, when the x64 build configuration has been created, I still cannot select it for the C++ project - only for the C# project.

I have done this before on another system - crea开发者_如何转开发ting an x64 config for a Win32 C++ project. But I can't do it now. Any ideas why? Something small/obvious no doubt, since google has offered no help. Thanks!

Maybe you didn't install the native x64 compiler.

Try to run setup again, and look if you selected the native x64 C++ compiler.
