I did in fact find it through the registry. It took a bit because once I found the key to it in HKEY_CLASSES_ROOT I did not see it in HKEY_CLASSES_ROOT > CLSID. So I did a search for the key in the Registry search and found it in HKEY_CLASSES_ROOT > Wow6432Node > CLSID. From there I was able to create a wrapper DLL, place that in my bin directory and then add a reference to it.
