| Hi guys,
this is for non-MAS.
Got the problem solved for now by rm-ing the old app.
Exception...drag install apps and Apple App Store don't leave receipts.
Our PackageMaker packages check HW/SW requirements, if OK it then finds/kills the process in case it's running, and deletes the old application (and maybe some other files if necessary) before installing.
We have a lot of Mac Packagers who don't always follow our guidelines (tough enough finding people who care to learn; some never learn and make a big mess out of things), and Help Desk and Desktop Support who sometimes delete old receipts (hard to break old habits when there is a rotating door).
In our case if we relied on PackageIdentifier or the presence of receipts we would be building a house of cards. :(
YMMV Don

This is automatic behavior with Apple's Installer.
As long as you use the same PackageIdentifier for all versions of your package, any files that exist in a previous version of your package that do not exist in the current version of the package are removed.
Again, this requires that you use a consistent PackageIdentifier, and also that the receipt(s) for the prior install(s) are present (without this, Installer has no way to determine which files are now obsolete).
If this behavior is not sufficient for your needs, you'll need to write a preinstall script that removes obsolete files.
