After uninstalling a Lexmark S310 printer for one specific user, we'll call them UserX, Acrobat X Standard still defaults to the Lexmark S310 printer even though it doesn't exist in Windows anymore. All other users it works correctly, this only affects 1 user, UserX. All other programs work fine for UserX. I spent 30 minutes on the phone with Adobe support who proceeded to tell me that Adobe doesn't store any information in users profiles and that it was a Windows problem, yet their software is the only one having a problem, a complete waste of 30 minutes. I have deleted all the Adobe profile information from c:\users\userx\appdata\local\adobe, c:\users\userx\appdata\locallow\adobe, and c:\users\userx\appdata\roaming\adobe and it still does the same thing. I am at my wits end and about ready to delete the profile and recreate. Anyone have any ideas so I don't have to go that far?
