Each time I try to click on ANY file folder or desktop icon, windows installer starts and begins re-installation of the 9.5 upgrade! After installing 9.5.1, same problem There was no such problem until I upgraded form the orignal software Adobe Professional 9.0. I have windows Vista Home Professional with service pack 2. ALL installs of Adobe at all times seem to go to completion without a problem. I've tried restarting my pc many times. Suggestions?
