Reset IDM Activation / Trial

  • This option also can be used to restore status if in case the IDM reports fake serial key and other similar errors.

  • PowerShell method to run IAS is supported on Windows 8 and higher.

Advanced Info

  • To add a custom name in IDM license info, edit the line number 21 in the script file.
  • For activation in unattended mode, run the script with /act parameter.
  • For reset in unattended mode, run the script with /res parameter.
  • To enable silent mode with above two methods, run the script with /s parameter.

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.



  • Minor bug fixes
  • Add an info to inform users that empty registry keys are being deleted when script deletes a lot of them
