The difference is that if the installer isn't creating the shortcut isn't being created correctly, it needs to be fixed, regardless of if there are other problems. Since nobody else has complained about problems with the shortcut, I guess it is fine. Stefan can't test the software under a 64-bit Windows environment because he does not have a 64-bit processor or a 64-bit OS. Don't expect him to program compatibility for things before he has a chance to try them
vvv x64 is a different kind of beast. You can't test your software on it without new hardware. x64 isn't even fully supported by major manufacturers yet.
