Adobe Acrobat 8.1 has stopped working.. Acrobat Reader same.. Vista..

[_LNail_]

I have installed Reader 8.1.2 and Pro 8.1.2. Pro doesn't even show a splash screen on starting up and goes straight into windows alert dialog that "Adobe Acrobat 8.1 has stopped working". "No known solutions are available".

Reader will show a splash on start-up and then go into the same windows alert dialog.

I've uninstalled and re-installed several times today. It was working fine last evening. Today it won't startup. There has been NO changes to the computer or software during this time.

Does anyone know of a fix or a workaround? Mission-critical machine here.

This is a long shot, but I just installed 9.0 on Vista Ultimate 64 Bit SP1 and have a similar symptom. In my case, I understand a small piece of the problem, to wit:

My users homed on C: can run the Reader with no issues.
My users homed on D: cannot run the Reader (Stopped Working).

Does this sound familiar to anyone? If so, is there a known fix other than moving the users to C:?
