Imatest may be installed on several computers, but an Imatest license can only be activated on one computer at a time. To move Imatest from one computer to another you first need to deactivate it. These instructions apply to computers that are offline, not connected to the internet, or are behind strong firewalls that prevent Online Deactivation. If your computer is online, you can follow the simpler procedure in Online Deactivation. After you’ve deactivated, you’ll need to perform Online Activation or Offline Activation on the new computer. Please note that in early 2019 we have transitioned to a more robust Licensing Platform. Depending on your software version, you may need to update your software prior to any activation attempts.

For versions 4.1 to 22.2, see classic offline deactivation.
