It can really be tough when you want to get your Patch Management system upgraded to the latest version, Patch 6.2. Especially if, throughout the history of your Altiris database, you have moved it, restored it, etc. without using the Altiris AppID account in those procedures.
Make sure that you remember log in as the Altiris APP ID to do any type of database maintenance, when installing or upgrading Patch or other solutions. This will make the upgrades to those solutions much easier.
