Error installing Explorer extension of 64-bit version on Windows 11

[KuroSynthesis]

I have made a clean installation of the program, first uninstalling the 32-bit version with the Revo Uninstaller program to avoid leaving residual files and after restarting the computer and trying several times to install the 64-bit version it gives me the error shown in the following image:

After that screen, the installation is finished and it works correctly.

Another problem with the 64-bit version is that the option to open the program does not appear in the context menu, having to go to the start menu, open the program manually and drop the folder with the files to be edited.

The rest of the functions that I use normally works without problem.

The error message is pretty clear: the Explorer shell extension is already installed from another folder.

This implies that the Revo Uninstaller was not advanced enough to perform all the steps the Mp3tag uninstaller is performing, including unregistering the sparse package that is used for the Explorer shell extension.

This is also the reason why you don't see the context menu entry.

You can try the following:

1. Uninstall the 64-bit version
2. Install the 32-bit version
3. Uninstall the 32-bit version using Windows Add and Remove Programs
4. Install the 64-bit version
