It is important to note that the checks and workarounds described are all targeted at the owner_sid and owner columns in sysdtspackages. The owner is also held in the CreatorName property of the package object itself. This is a read-only property which cannot be changed programmatically.

Each time you save a local package, a new row is written to sysdtspackages, using the values held in the package object. This means that changing the value of the owner column will not be a permanent solution as next time you save the package, the new row uses the package Creator property which has not changed. They only way to permanently reflect a change of owner is to use the Save As function in the DTS designer. This creates a new package, not just a new version of an existing package.
