Recently my institution took the plunge and made the move to adopt Creative Cloud. As part of the switchover from CS5, I'm being used as one of the guinea pigs.
Upon first-time installation of the provided Creative Cloud package (which has installed correctly for others in my office), my iMac shut down, this obviously interrupting the installation. After restarting I Googled what to do and found forum entries on what files to remove (as there were some left over form the first installation) and followed them.
Unfortunately, when I try to install the package it fails with a generic message, and nothing is installed. I also can't run the uninstaller (same error).
