Common Activation Issues
Below are the 3 main types of activation issues:
- Connection to the server failed.
- The product key has already been activated on the maximum number of computers
- The key is not valid
Connection issue to the activation server
If the activation window appears to be unresponsive after hitting Activate, it may be an indication that there is an issue connecting to the activation service.
You may also see the message "Connection to the server failed.":
This issue occurs due to the following reasons:
- A firewall is preventing connection to our activation server
- Network congestion or connectivity issues
In both circumstances above, visit the following link for instructions on how to activate manually:

The product key has already been activated on the maximum number of computers
This will occur if the serial number entered has already been used for activation.
Any user may have up to two devices activated per license provided only one license is being used at a time. By default, SigmaXL licenses have one activation.
Contact support to enable a second activation for another computer, for example a work laptop or home computer.
The key is not valid
The above issue can be resolved by following the steps below:
Copy (ctrl+c) and paste (ctrl+v) the number into the serial number field in the activation window:
Activation on MacOS
Note that copy/paste does not work on the Mac
If the product key must be entered manually, be sure to include dashes. When manually entering the serial number, note that number 1 is not used and will always be the letter I.
Contact support for help determining which version your serial number is eligible.
