I need help about how can i use the file licence.avastvpn in my mac

I payed for this licence but i don´t find help about the installation using this file (licenve.avastvpn) in Mac OS X. The application SecureLine need a activation with a serial key, but i have a file licence only.

Hello,
macOS version doesn’t support license file. Please contact our support (https://www.avast.com/support) and ask them to exchange your license.

Best Regards,
Martin

Good, now just have some patience and wait for avast to handle it.
