XML syntax error: The specified protocol is unknown

I have succeeded to install the latest SandCastle and Help2 on Win2012. Yet, the following error raises during compilation. Any help is appreciated

Compiling MS Help 2 file...

Check the indicated file at the indicated location. Since it lists the resource too, at a guess I'd say something with the Help 2 compiler is still not registered correctly as it isn't recognizing the "MS-Help://" protocol.
