You need a license key

The software does not run without a license key. For a free trial, Noldus sends you a trial license key by email. You cannot generate a key yourself.

  • The trial lasts 14 days, starting from the moment you activate the license.
  • The trial includes all modules of the full license, with the same look and feel.

How to get a free trial

  1. Open the download link for your product (see the table above) and download the installer.
  2. On the same page, scroll down to the form, choose Free trial under "How can we help you?", and send it.
  3. Noldus emails you a trial license key.
  4. Install and start the software, then activate it with the key (see below).

Activate the trial license key

The steps are the same for most products, for example FaceReader and The Observer XT:

  1. Start the software and choose Activate software license key, then click OK.
  2. Select Floating or Fixed activation, then click OK.
  3. Enter the license key you received by email and click OK.

You can see how many trial days are left under Help > About (in The Observer XT: Help > About The Observer XT > License info).
