I've tried it all...still can't get mp3tag installed

If that also fails, delete anything from MP3tag in the program files folder and the %appdata%\MP3tag folder and see if that helps.

Please repeat your uninstallations until this Powershell command
Get-Package | where name -like Mp3tag* | Select-Object -Property Name, Version, FastPackageReference
does NOT show any information like this anymore:

Also the Powershell command
Get-AppxPackage -name *mp3tag*
should not return any information anymore.

@rockman5150

there are no registry entries for mp3tag anywhere in the registry

Please double check your registry with this two CMD line commands:
reg query HKLM /s /f Mp3tag
and
reg query HKCU /s /f Mp3tag
there should be shown no information anymore.
