Build 2847 broke my Comodo - Class not registered :(

The last successful update on my machine was just before a program update from build 2813 to 2847
(Please see attached image), now the signature file downloads fine, but the install fails with ‘Class not registered’.

Is there any way to get Comodo to produce a verbose log? If I knew which class isn’t registered it might be fixable…

Diagnostics found no problems - Results attached
