I've seen this mentioned several times in this forum, but I can't find a definitive post on how to do it. When I change the registry key HKLM\Software\Veritas\Backup Exec\Engine\Misc, I get a 'Database not found' error when I try to start the BE services. I also shut down the BE MSDE instance when attempting this.
This is BE 9.1 on W2K.
