I am receiving an error when trying to launch Adobe Reader or open a .pdf file. The error says in its own little window "An Internal error has occurred". I have tried uninstall and reinstall with no luck. The current version i have installed is Version 9. The computer is not part of a domain however the regular user has only "user" permissions. I have tired adding the user to the "power users" group but this did not solve the issue. Only after adding the users to the "administrators" group did Reader open without errors. The box is XP Pro SP3. Apparently there is some sort of permissions issue. I have setup Reader 9 on other boxes but they all have SP2 so I am guessing that the SP3 is the issue. Anyone know a work around or have this same experience?
