Thank you for your feedback!
I think I misunderstood the issue described earlier.
From the picture, it appears that the installation program does not have permission to add KeePassXC under C: \ ProgramData \ Microsoft \ Windows \ Start Menu \ Programs. It refers to not having access to the C: \ ProgramData \ Microsoft \ Windows \ Start Menu \ Programs folder
You need to check the permissions of the folders in the path step by step
Also, is user an administrator account? The following methods can be used to check
Press win+r, enter the command netplwiz to check if it belongs to the administrator group
Additional suggestions, I'm not sure if there will be other strange permission restrictions. Can I install this PC completely new after buying it back?
