Try installing it in a virtual machine, with a version of Windows that worked. Then, go into the registry editor, click "HKEY_CLASSES_ROOT", press Ctrl+F to bring up the find dialog, and then search for "76f61208-6a7f-402e-bae5-40c9562aa893". There may be a sub-key called "InprocServer32", which usually contains a default entry with a path to the component's DLL. If the key doesn't contain that sub-key, it may reference other GUID's that you can search for, which may then have a path to the DLL, under "InprocServer32", or some other sub-key.
