Registering the dll created by add-in wizard gives problem

We created an add-in for a specific task with VisualC++ 6.0 on a workstation running on windows2000. Now when we try to register this add-in dll on other workstations running on windows 2000, it runs fine on some and on some others it gives this message,

"Unable to register this add-in because its dll register server returns an error".

On w2k you have to have administrator rights for some keys in registry. Try to run it under another user accaunt. Also you can check your code and see with which parameter RegCreateKeyEx called.

If that doesn't help then maybe its time to add lots of debug logging / error checking. Also why not remote debug it.
