How does it work?

  • IDM stores the data related to trial and activation in across various registry keys. Some of these keys are locked to protect them from tampering and data is stored in a pattern to track the fake serial issue and the remaining trial days. To activate it, script here simply generate those registry keys by triggering a few downloads in IDM and identifies those registry keys and locks them so IDM can’t edit and view. That way IDM can not show the warning that it’s activated with a fake serial key.


  • Browser Integration Fix: Chrome FireFox
  • Reach out to us on Discord (signup not required) with an error screenshot.



  • Move the project to Github and
  • Minor bug fixes
