My other computer has flipped out. When I try to start it, it gets stuck attempting to install or set up something called Document Viewer. This throws a .NET error dialog box saying that an unhandled exceptoin has occurred in a component in my application. There are only options to continue, or look at the details. I can’t cancel out, and I can’t stop this from happening. At the moment, I can’t even shut it down, except by pulling the plug or pressing the power button. The computer running XP and was working fine yesterday. Has anyone else had this problem? ---

Something in your Startup Items might be causing that. Have you tried booting into safe mode? I think that you need to hit F10 in the Windows bootloader to get into safe mode. ---

Its F8 actually once you get into safe mode see if you can delete it. Try to delete the folder in the Program Files and do a run command and type msconfig and disable it if you see it. ---

Better yet just hit a valid restore point–if you’re talking an Adobe product you’ll never get it out of there without a full fumigation tent and restore is easier by a long shot.
