Cannot write configuration file
If you're getting the error message Cannot write configuration file when closing Mp3tag, it's most likely a file permissions issue.
This can happen if you recently updated your Windows version or moved data from one computer to another. In this case, the file permissions sometimes reference Windows user accounts that do not exist on the updated computer or are not the one which you're currently using.
To resolve this, the file permissions need to be adjusted. How to do this is described in the following steps
- Open Windows Explorer and enter
%APPDATA%to the address bar
- Locate the folder
Mp3tag, right-click and choose Properties from the context menu
- Open the Security tab which allows to view the permissions of this folder
- Choose Edit to change permissions of this folder
- In case your user name is not listed in the list of permissions, choose Add and provide your user name and make sure that you allow Full control
- Make sure that your user account has full control to this folder
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 <path to Mp3tag installation> regsvr32 Mp3tagShell.dll
