Geneious Prime uses a licensing system that requires on-line activation.
Geneious Prim needs to be able to connect to the website https://licensing.biomatters.com and https://licensing.geneious.com (using the standard https port 443). If access to these sites are blocked by a firewall then Geneious will be unable to register the license activation and will run in restricted mode.
You may need to configure proxy settings to enable Geneious Prime to access the licensing site. See the following for instructions on how to manually configure proxy settings: Connecting to the internet from within Geneious.
