IDM Activation Script​

An open-source tool to activate or reset the trial of Internet Download Manager


  • IDM activation with registry key lock method
  • Activation persists even after installing IDM updates
  • IDM trial reset
  • Fully open source
  • Based on the transparent batch script

Download / How to use it?​

  • First, fresh install Internet Download Manager. Make sure previous cracks/patches are removed/uninstalled if there are any.
  • After that, follow the below steps to activate it.

Method 1 - PowerShell​

  • On Windows 8.1/10/11, right-click on the Windows start menu and select PowerShell or Terminal (Not CMD).
  • Copy-paste the below code and press enter
    irm | iex
  • You will see the activation options, follow the on-screen instructions.
  • That’s all.

Method 2 - Traditional​

  • Download the file from GitHub or Bitbucket
  • Right-click on the downloaded zip file and extract
  • In the extracted folder, run the file named IAS.cmd
  • You will see the activation options, and follow onscreen instructions.
  • That’s all.



  • This script applies the registry lock method to activate the Internet download manager (IDM).
  • This method requires the Internet at the time of activation.
  • IDM updates can be installed directly without having to activate it again.
  • After the activation, if in some cases, IDM starts to show an activation nag screen, then just run the activation option again without using the reset option.

Reset IDM Activation / Trial​

  • Internet download manager provides a 30-day trial period, you canuse this script to reset this Activation / Trial period whenever you want.
  • This option also can be used to restore status if in case IDM reports a fake serial key and other similar errors.

OS requirement​

  • The project is supported for Windows 7/8/8.1/10/11 and their Server equivalent.
  • The PowerShell method to run IAS is supported on Windows 8 and higher.

Advanced Info​

  • To add a custom name in IDM license info, edit line number 29 in the script file.
  • For activation in unattended mode, run the script with the/act parameter.
  • For reset in unattended mode, run the script with the/res parameter.

How does it work?​

  • IDM stores the data related to trial and activation 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, the script here simply generates those registry keys by triggering a few downloads in IDM,identifies those registry keys, and locks them so IDM can’t edit and view them. That way IDM cannot show the warning that it’s activated with a fake serial key.


Some may have encountered that the serial numbers are fake prompt. Nag attach nako possible fix.

Update 04/20/2024:​
