I just purchased the MyDVD Video Lab, W7 compatible version yesterday. When trying to open any application, I get the "No permissions to launch application error". I have uninstalled and reinstalled the software, thinking there might have been an error upon istillation to no avail. I am operating this software on a Sony Vaio, I7 920 processor, 6GB RAM, 500 HD, and a 64-bit W7 OS. Please help, I am just trying to upload a version of the movie I made in MyDVD 8 - but this is not compatible with W7, or recreate the video if needed. Just frustrated that I spent money on this software and can't get it to work. Please help!!!
