Hi. I downloaded the student edition for vista and am having a prblem inatalling it. I go to install it and get the message box that says that windows installer has stopped working. Then another box comes up for Data Execution Prevention, DEP and how to turn it off for certain programs. Tried turning it off for just the solidworks setup, didnt work. then i found windows installer, tried that, message came up saying that DEP must be enabled on windows installer. Is there an upgrade or something that will allow me to install this???
