Unhandeld exception on startup

image

(other than windows update) No change in other software since last working SGP.

SGP silently quits if I continue.

When you say

Does this mean you see this exception after upgrading to a newer version or that SGPro is unchanged and it started happening all of a sudden?

We saw something similar years ago here:

We made the changes that @Chris suggested. Not really sure why this pops up… maybe somebody else has seen this? It never usually fixes anything, but you might try to uninstall ASCOM, download the latest and reinstall. I see your tests passed, but there is no guarantee of test coverage for this particular issue.

SGPro is unchanged and it started happening all of a sudden.

I’ve thrown a bunch of stuff at it. Re-running the SGP installer, installing the latest .NET, virus scan. So far no joy.

Now the machine is updating to windows 1903. Will report back.

repairing ascom did the trick.

It may be worth running this past the ASCOM people. Your SplashForm shows a problem with loading an ASCOM component. Maybe the repair installed something that was missing the first time.
