prerequisites: the hot key for the snipping tool is off
- I uninstalled Lightshot
- then I installed the following updates: 2023-08 Cumulative Update for .NET Framework 3.5 and 4.8.1 for Windows 11, version 22H2 for x64 (KB5028948) 2023-08 Cumulative Update for Windows 11 Version 22H2 for x64-based Systems (KB5029263) 2023-08 Cumulative Update Preview for Windows 11 Version 22H2 for x64-based Systems (KB5029351) 2023-08 Cumulative Update Preview for .NET Framework 3.5 and 4.8.1 for Windows 11, version 22H2 for x64 (KB5029718)
- restarted the laptop
- then I ran the Lightshot installation with Admin permissions ("run as administrator" option in the right-click menu for "setup-lightshot.exe"
and it works for me now :)
