I have several plug-ins that will not install in CS5.5.
These are older versions of a few plugins that work in CS5.5 but will not properly install since the installation package is looking for CS5. I have them installed and working now, but I am wondering how I can get CS5.5 to be the main version of CS on my system again? I tried to go into Programs and Features and see if I could simply do a repair of the installation but Adobe only offers uninstall options. I'll keep looking. I realize now that I should have installed CS5 then CS5.5 but I have a streamlined clean build that I spent 3-4 days on and don't want to start from scratch.
For the projects, open the program first, then you can open any project from within the program.
Don't know much about the plug-ins.
Cant you just right click a premiere project and choose "open with" and then just choose the program you want to open those files.
