Pulsar dome error code

In the drop down list for choosing your dome I get the option “Pulsar Observatories Dome”
I can select it but when I go to settings I get an error.
“ Retrieving the com class factory for component with CLSID (6ECD5F86-_5654-4D0D-B816-0336CA6FF7C5) failed due to the following error: 80040164 Class not registered (Exception from HRESULT: 0x8004154 (REGBD_E_CLASSNOTREG)).
Any help to resolve this would be very welcome.
The dome works perfectly with the Sky x and using the dome software provided.

That’s typically an indication that your driver is not designed for the “bitness” of SGP that you’re using. You have a couple of options:
1 - use the ASCOM Device Hub
2 - use a different Bitness of SGP (if you’re using 64 then use 32 or vice versa)

Thank you,
