This annoying problem has come up a couple of times. Here's are the things that have worked to get folks unstuck:
- This guy couldn't uninstall or install, but found a trick: http://blog.underplot.com/blog/10/
- This thread tried that guy's same trick, but when it failed ran the Windows Install Clean-up: http://forums.adobe.com/thread/427487
- Same advice here plus directions for how to capture the installer log: http://forums.adobe.com/message/3294423
- After trying the above three things with no success, one customer rebooted and suddenly all was well. There's a reason Customer Service peeps like to ask you to reboot a lot!
