I'm using CS6 in a class, and one of my students used CC12 to complete his project. Since CS6 can't open a CC12 project, I want to install CC12 onto my computer to open and view it, but I want to make sure that it won't screw up my ability to open up everyone else's projects who are using CS6. Also, I don't want to use CC12 because our school only has CS6, and I don't want to do anything at home that I can't bring to school.
In the past, I've had trouble with installing dupliate versions of a software, and don't want to have to uninstall, and reinstall CS6...
