How can I check if an ActiveX dll is already registered?

Question

I have an installer that is registering several dll's and need to know if this was successful.

Answer 1

This seems to do the trick for me: http://www.nirsoft.net/utils/registered_dll_view.html

Answer 2

I would like to let you know all registered COM class objects are listed under HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\. We can navigate to this location in registry editor, highlight CLSID and press Ctrl+F to search the dll/ocx file.
