This white paper is to address a situation where you are trying to update to a newer HFA, but CPUSE says it is trying to uninstall an older hotfix, and the older one doesn’t exist. CPUSE says it’s there and installed, but cannot uninstall it.
This could happen when trying to restore from an older backup.
The key is finding the Package Key which is hidden, restoring the repository for that package, then uploading the older package. There is an SK will direct you to TAC, but there is also another way to gather the information you need.
