I have come across your posts and noticed that you installed FCP7 successfully. Like others above, I too like to use 7 for long form projects and X for quick and color fixes. Starting today FCP7 would not open. I have tried to open the program from a project or the launch and no luck. I thought that a new install would be the answer. It’s not. I’m told that my installation has failed. So I come to you for an answer; Do I need to remove other parts, (compressor, iDVD etc. in order to have a successful installation?
