Short Guide Software Licensing (Offline Activation) - ZEISS License Activation Utility (ZLAU)

If you click on a system to be updated in the "Software Licensing" feature, you have the option of updating the software licenses for your measuring instruments under "Request License Key". The prerequisite for this is a valid software maintenance agreement.

When you click on "Request License Key", a window will open asking you to confirm that you actually want to update this license. 

You will receive an e-mail with the Entitlement ID, which is required for the update. This ID needs to be entered in the ZEISS License Activation Utility (ZLAU):

Step 1: Start the ZEISS License Activation Utility program (available in the Software Download Portal).

Step 2: To activate licenses, click the "Manage Licenses" button.



Step 3: Select "Activate license" under the Action tab on the left and "No Internet connection available" under Internet connection on the right.



Step 4: Enter the Entitlement ID contained in the email and click "Add". 



Step 5: By clicking on "OK" you will be asked to save an "activation_request.xml" file. Please send it to

Step 6: You will now automatically receive a "*.xml" file (for PC-bound licenses) or a",*.lic* file (for dongle licenses), which you can import to your CMM computer. After receiving this file, you must import it into the ZEISS License Activation Utility (ZLAU). For detailed instructions on importing license files, please click here.
