Hi,
Before troubleshooting this issue, please note that activation is required only by FreeMASTER Lite component, in case you are using FreeMASTER (main desktop application) just disable Lite feature in component selection step during installation process.

Troubleshooting:
- Make sure you have admin rights on your machine, as there may be some settings blocking the communication between your computer and the licensing server (ex: a firewall).
- In case you cannot run the installer with admin privileges you can try an offline activation. The process is similar to the one described in this post HOWTO: Activate S32 Design Studio. Note that it is not excluded that you may run into into other issues due to limited access rights.
Hope this helps,
Iulian
