Acrobat 8 (really 8.1)

Yesterday I upgraded from Acrobat 7.0 to 8.1. Naturally it didn't work. Acrobat would not start and instead I received an error about .joboptions. Adobe tried to be helpful and repair it by re-running the installer. Naturally that did not work. Neither did the tried and true uninstall-reinstall method.

The error was about the following files being inaccessible.
"C:\Documents and Settings\All Users\Application Data\Adobe\Adobe PDF\Settings\*.joboptions"

The solution is straight forward. Permissions on "C:\Documents and Settings\All Users\Application Data\Adobe\Adobe PDF\" were incorrect. The SYSTEM user had Full Control, but Everyone and Administrators only had Read permission. Not even List Folder Contents. Giving the Full Control permission to the directory let Acrobat run properly as the subdirectories were now accessible.

Update:
The exact error message is:

Unable to find "Adobe PDF" resource files.

"C:\Documents and Settings\All Users\Application Data\Adobe\Adobe PDF\Settings\*.joboptions"

Do you want to run the installer in repair mode?

You may also need to change the permissions for Adobe PDF and all the subdirectories. Otherwise you'll get messages from about Windows Configuring Adobe Acrobat when you try to right click and/or open Office programs.

And so it begins

Nothing much to say here. I just plan to post interesting computer problems, solutions and information. Hopefully others find it helpful.
