COM DLL Location - Windows Registry


Given a COM Class Name (e.g., ObjectLibrary.MyClass), how do I find the DLL behind it?


1. Open Registry Editor

2. Navigate to HKCR\MyClassName\CLSID and get the Default value, which should be a GUID. Use this GUID in the next step.

3. Navigate to HKCR\CLSID\MyGuid\InprocServer32. Its Default setting should be the COM DLL.
