[DUG] Registering DLL's

[David O'Brien]

We have multiple DLL's that get registered on install for one of our products. Lately for 2 out of 1000's of users the registration fails for one of the DLL's.

The particular DLL can't be registered manually, regsvr32 hangs. It drops back to the command line after 3 or more seconds, but no messages, needs to be killed in task manager.

I would suspect it to be the DLL that's at fault, but logging on as another user on the same machine it registers fine and works for that user. Even though it's registered by the second user, it hangs when trying to be loaded by the original user. All the other DLL's register and load fine, so I don't think it's permissions.

This is happening for 2 users in 2 different companies.

Windows 10 Pro machines, pretty well up to date.

Any ideas?

Regards,
Dave.
