TypeLib entries not removed on uninstall

[Cygnusx1]

I am using the Class, ProgID, and the TypeLib tables to register my files. Yet on uninstallation only the TypeLib entries are not removed. The permissions are set correctly.

Any ideas?

Did you take a look at uninstallation log?

The log:

un-regersting the file prior to uninstallation makes no difference with the log file. However, the TypeLib registry entry is removed.

Removing all Merge Modules allowed the uninstallation to work completely.

The questions is why?

I don't know. You will have to narrorw it down, and identify the merge module causing this problem. Once identified, it is then possible to pinpoint what causes this problem.
