Add a license firewall exception

If you have difficulties activating your Provar license, you may need to whitelist our licensing servers. One of the following error messages may be displayed if there is a server communication error: 

  • “Failed to activate LICENSE_NAME: The floating license server is not currently available”.


How can I whitelist Provar servers?
