  1. I get an error…
    “Your current key (0QY8D2-KJ7EF0-WQUXJ0-QNVM5Z-BD6AYQ) is not valid for this version. Please find your installation key in our customer area.”

    The window the error pops up in also has a box to enter a new installation key. Only options are Paste from clipboard button and cancel… next button is grey out I assume til a new key is entered…?

    Please advise. Thanks.

  2. Thanks for the work, but the latest version (TreeSize Professional Full) doesn’t work. When trying to run it, it immediately crashes without any notice. This is on a fresh install too, previous version removed entirely.

  3. When I run as admin the “Install-x86.bat” or “Install-x64.bat” it does nothing, but when i just run it the there’s a message says “access denied” and continue installing it, when i run the program it is asking me for the Installation Key
