I have a simple task: to make sure that a given dll is indeed registered in a Windows system.

The only thing I could think of is: to extract a CLSID from the DLL's TypeLib and check it against Windows' registry. This way I can be 100% sure that this exact file is registered, and not just any DLL with the same name.

The question is: how can I reliably extract TypeLib's CLSID from an unregistered DLL? I've been able to do it through hexdump/regex, but in the end I'll be just guessing where it is, and it might fail eventually.

Is there a way to make the DLL spit it out for me? Just the way it does to the registry when the registering function is called?
