I was getting the same error message under Vista Ultimate. Uninstall and Reinstall did not fix it. But I went to c:\Program Files\Ulead System and right clicked on the vstudio application. I set it to be compatible with Windows XP SP2 and set to run as Administrator. Then Ulead worked fine. I then turned off the compatability and the run as administrator. It still works fine. Maybe this will work for someone else.
