Not sure if this uninstall key thing is root cause of the issue I’m about to report.
Install from microsoft store. uninstall from Apps & Features, uninstallation completed and the icon is removed from the list. No traces at all. Looks clean.
Install from .exe binary downloaded from this site. Uninstall from Apps & Features, uninstallation completed, but the icon still stays (inactive but gives uninstallation option).
You have an old version listed installed somewhere else on your computer.
From the start of your video:
When you installed Shotcut. Notice the version number.
After you uninstall Shotcut 22.03.30
A different version is already installed on your computer. It was there before and after your install/remove demonstration. Version 19.12.31 was installed on 2022-02-12.
Honestly, didn’t notice the version. Thanks for reviewing it and finding a bug in a bug report… Let me check the old version traces and retest. Will unlist the bug report video as it no more stands true.
