  1. I have already tried it but error occurred:

    Access is denied.
    Error occurred while processing: extension.

    1. as descrived above, you need to elevate your command prompt
      that being said, as I tried it didn’t seem to take an effect. in windows 10 version 2004
      you can confirm your new assoc but the file is opened by the old program anyway
