Activate Offline

Imatest may be installed on several computers, but an Imatest license can only be activated on one computer at a time. To run Imatest, you must activate your license. This page shows how to activate Imatest software on a computer that is offline, disconnected from the internet, or behind a strong firewall that prevents Online Activation. If it’s online you can follow the simpler procedure in Online Activation. If you are moving an activation from one computer to another, you’ll need to perform Online Deactivation or Offline Deactivation first.

For versions 4.1 to 22.2, see classic offline activation.
