"My Studio plus version 11 also would not work (open) in Windows 7. Tried this and it worked. Give it a try....go to control panel, trouble shooting then Programs (run programs made for previous versions of windows). It gives you a list of programs, find Studio and try the settings made for Vista. There are a few different options, this one seemed to work for me. Good Luck."
