Pegasus Astro Forum

When I try to Open the newest Unity program on my observatory computer it flat out won't run. I made sure power was on the Pegasus although that shouldn't keep the program from running it simply wouldn't find the UPBv2 correct? I ended up having to uninstall and reinstall the program to get it to execute. Trying by Run as Administrator didn't work, rebooting didn't work but uninstall/reinstall did. I also made sure it was the newest build, which as far as I can tell, isn't listed in the download title but was downloaded and installed again today. The previous one was installed several weeks ago when I started to use the unit. The notice of an update was followed by my downloading and installing it over the current older version.

I have no idea why this program wouldn't run before the uninstall/reinstall, even after a clean reboot.

Mine has seemingly come up blank too - but the server is running and I can connect through ASCOM still.

When I look at Task Manager, only the server is running.

Same problem here. Was working fine, but after re-booting after latest windows update, Unity no longer loads.

Update:

Downloaded latest version (1.6.1062.39) and it loads now.

I presume this was a fix.

Yes, had to do with a recent windows update (it happens under certain circumstances). Please upgrade to the latest Unity which fixes the issue.

Hi Evans,

It could be great to add the update version number into Unity Platform filename. i.e. PegasusAstroUnityPlatform_v1.6.1202.43 Thanks!

Regards,
Yves

I have the same problem and it disappeared after the update, just want to confirm it.

Same problem for me with latest Unity Platform 1.6.1230.46 and latest Windows 10 Pro 22H2 19045.2251. The Unity splash appears as normal then dissappears but no UI is shown, and task manager shows only Peg.Server. Reverted to previously installed 1.4.36.5 and everything works again.

No issues have been reported with latest Release Version : 1.6.1230.46
I tested with Windows 10 and 11 with latest updates

Check and delete c:/Windows/temp/ files you should have a conflict file named "autofac" there.

no "autofac" present in temp but cleared anyway and rebooted, same issue. Windows error report shows:

UPDATE: The problem was due to Unity being installed on D: drive where I install all my non-system apps. Removing it and reinstalling to C: drive worked. Removing it again and reinstalling to D: drive failed, so the issue appears to be repeatable. Perhaps there is a .NET configuration setting that is harcoded for the C: drive?

Thank you for reporting this. We'll investigate why this happens.
