There seems to be information out there on handling and resolving the issue when searching the error message and code using either Google or DuckDuckGo. Have you tried any of these troubleshooting solutions?
Of course i have checked online, I have asked them to try run as admin but as yet have not had a response. Getting them to run repairs is not a path I want to go down. I would assume this would of been a common Xojo problem, or at least someone has come across it.
Are you embedding the Windows Universal Runtime with your build? If so, try one without it using the native one included in the system and see if something changes. Also check if some antivirus played with your files.
I am not including dlls with my build. I have asked them to try turning off any antivirus.
It was working just fine yesterday and then updated on a shutdown of windows, then this morning the error appeared.
Also sent them another app to try.
I’m thinking that Microsoft C++ 2015+ redistributable might have been corrupted during Windows Update. I noticed on Windows 11 it shows a lot newer version 2015 - 2022 version 14.32.XXXX while the one included with Xojo is 14.0.24XXX. I doubt I can get them to remove and reinstall the older Xojo one as other applications could be relying on newer redistributable.
I asked them to get the version installed to do a modify - repair and see what happens, however getting responses from users is like annoyingly hard sometimes.
