    Indeed. The graphics are definitely too much, but I'm not sure if the zip file contains anything really terrible. Wimwizard's big mistake was posting a public version of his tool, then later promoting a paid version with more features.

    :tankyou:
    (the arm binary should come in both arm and arm64... I think, they did with adk10, I have not spotted that in adk8 :mushy: )
    But thank you kindly, much appreciated.

    Did the OP not provide readme's and powershell scripts?

    Yes, just looked in the zip file...
