You would have to check in Help\>About if you have a standard or a portable installation.
Then see if the FAQs about the shell extension help you:

> Right-click context menu is missing on Windows 11 Assuming you've already restarted explorer.exe via the right-click context menu in Task Manager (or have rebooted Windows), this is happening sometimes on Windows 11 for reasons which I still trying to find out. What might help in those cases and when the classic context menu is preferred, is to manually register the shell extension from a command prompt with admin rights: cd \ regsvr32 Mp3tagShell.dll
