When purchased, our Qlik products are delivered with a 16-digit license key (LEF) and/or the Signed License key (SLK). What key is applied may differ depending on your requirements or the version of the product. See The Qlik Signed License Key and the License Enabler File for details.

To manually obtain your LEF:

  1. Make sure to have the 16-digit license key at hand
  2. Open the LEF Server (http://lef1.qliktech.com/manuallef/default.aspx)
  3. Type in the license key
  4. Check the "I'm not a robot" box and complete the identification task if prompted
  5. Click Request LEF
