Is it OK to run both Premiere 3 and 7 ? There are features of both that I like. I was running both versions of Photoshop (5 and 7) and had no problem doing so until I used Adobe e-mail and that corrupted a file/folder ( trying to edit the contacts list caused crash/freeze) that only Adobe Tech help could resolve. I don't want that to happen with Premiere.
There is no problem running both versions, however if you open a PE3 project in version 7 you will not be able to edit it again in version 3.
