{
#if defined(_WIN64)
return TRUE; // 64-bit programs run only on Win64
#elif defined(_WIN32)
// 32-bit programs run on both 32-bit and 64-bit Windows
// so must sniff
BOOL f64 = FALSE;
return IsWow64Process(GetCurrentProcess(),&f64) && f64;
#else
return FALSE; // Win64 does not support Win16
#endif
}
