I don't have an explanation for the error you're getting, though. If you've uninstalled, it should now longer be available and installing on a new location should be now problem. If you have any details on the type of user account you're using (and if it differs from the installing user account) or anything else that might give a hint regarding the cause, I'd be happy to know.
Thanks Florian. I tried the powershell commands - same error (see picture below). I am using a standard admin account and it is the same as I have always used. It is windows 11 pro, upgrade install from win 10 pro, and an insider build, but not on the bleeding edge: 21H2 22000.708
I uninstalled x64, reboot, reinstalled x32, reboot, uninstall x32, reboot, checked right click menu with Nirsoft Shexview and shmnview - nothing there, then reinstalled x64 successfully without the error message. However, now I have the context menu item mp3tag, but it does nothing.
No output from the first PS command line.Here is what I got:
PS C:\Program Files\Mp3tag> powershell -c "Get-AppxLastError"
PS C:\Program Files\Mp3tag> powershell -c "Get-AppxPackage -name mp3tag"
Well, maybe the program did not register properly. The first 2 keys are not there at all
HKEY_CURRENT_USER\SOFTWARE\Florian Heidenreich\Mp3tag\Install\InstDir HKEY_CURRENT_USER\SOFTWARE\WOW6432Node\Florian Heidenreich\Mp3tag\Install\InstDir
The next is OK I think
The last one is not there at all
This all looks good — not all of the keys must exist, it's enough to have one of them. If the InstDir points to the correct installation folder (can you check that?) it should also be able to open the app.
Yes, "Open with" is something different and doesn't involve the shell extension.
I've created an unofficial version that includes extended error logging to a file Mp3tagShell-####.txt on your Desktop. This means, this version is only made available with the intention of gathering more information on the crash you're experiencing.
It would be great if you could install this version and reproduce the issue with different scenarios (one file, several files, directory) and send me the log file(s). You can also do so via PM, in case you don't want to share file paths logged to those files with the Internet.
