API NAME | Minimum supported client ------------------------------------------------------- GetModuleFileName | Windows XP GetVersionEx | Windows 2000 Professional VerifyVersionInfo | Windows 2000 Professional IsWow64Process | Windows Vista, Windows XP with SP2 ...... …

EDIT maybe this thread should be moved into another sub forum? not sure i'm currently programing a Shader Editor Tool to create on the fly own GLSL Shaders.
