Visual Studio 2008 x64 Build configuration manager setting

[come from http://stackoverflow.com/questions/5979675/visual-studio-2008-c-no-x64-platform]

If I recall VS 2008 Pro doesn't install the 64-bit compiler and tools by default. You have to explicitly select them during the installation.

1. Control Panel -> Uninstall Programs.
2. Select Visual Studio and click Uninstall/Change.
3. Wait. Wait some more. Click Next.
4. Choose Add or Remove Features.
5. Expand MSVC 2008 -> Language Tools -> Visual C++.
6. Select X64 Compilers and Tools.

You'll probably need your original installation media.

Once the 64-bit compiler and tools are installed, you should be able to add a 64-bit configuration to your solution.

위에서 시키는대로 하니 X64 설정이 나타났다.
