One two of our Macs Adobe Reader 11.0.4 with have an Internal Error on launch. One Mac is running Mac OS X 10.8.5 and the other is running 10.6.8. One user has a Portable Home Directory (so she is like a local user) and ther other has her home directory on a Mac OS X Server. Neither account has admin priviledges.
When I use the local admin account on both iMacs Adobe Reader will work fine, so the app should be OK. But it will not run on these two user accounts.
I am preparing more testing, trying version 10 and creating a new user account. Has anyone seen this problem before. I have done research on Internal Error but none of the solutions I found work for me.
