Vista or 7: C:\Users\<YOUR_USER>\AppData\Roaming\Quest Software\
3) Rename the “Toad for DB2 5.5” folder to “Toad for DB2 5.5 OLD”.
4) Start Toad for DB2 5.5.
5) When asked if you want to ‘Migrate’ settings from a previous version, choose “CANCEL”.
6) Connect to one database and exit Toad for DB2 again to finalize all the settings.
7) Start Toad for DB2 again (check & ensure Toad has been reset to factory defaults) and then re-test the issue.
