OK, so in the end I’ve managed to solve the problem.
It’s not a SGPro related issue, and it’s not an ASCOM related issue. It’s a Windows OS problem… having something to do with the fact that .NET 3.5 is not longer enabled on some Win10/Win11 OS releases…
The solution was presented here: Sequence Generator Pro ASI/ASCOM Connection Issue - Beginning Deep Sky Imaging - Cloudy Nights
which points to the SGPro forum, here: ASI/ASCOM Connection Issue - #4 by Ken
Basically I’ve uninstalled everything, meaning the ASCOM platform and all ASI/ZWO drivers, did the .NET 3.5 settings presented above, and installed everything up to date (ASCOM platform + all ZWO ASI were downloaded again, from their websites, to ensure I’m 100% up to date…).
Everything runs fine now, but my OCD tells me I need to keep a close eye on the Windows Features settings, as I have the “Automatic Updates” enabled…
All the best,
Bogdan.
