Your iLok license provides you with 2 activations. You can use dongle-based, machine-based, or iLok Cloud activation through the iLok License Manager.

In case you’re still using the Soundtheory copy protection: You can install and activate Gullfoss on several local user accounts and on different machines, provided that you are the only one using Gullfoss. For a single-user license, you get 2 machine activations and 3 cloud activations. Your machine needs a working internet connection when activating. Cloud activations require the machine to be online permanently when using Gullfoss. Cloud activations do not allow for concurrent sessions (i.e. only one computer can be using Gullfoss at the same time). We highly recommend using a machine activation so that Gullfoss will not be interrupted by internet outages or server down time.

You can also convert your license to iLok by going to your account page and click on the ‘Convert to iLok’ button.

Close the cloud session in the iLok License Manager and activate your iLok license on your machine or dongle.

In case you’re still using the Soundtheory copy protection. To switch from your current cloud activation to a machine activation, please perform the following steps:
– Download & install the latest version of Gullfoss
– Open Gullfoss and click on the logo
– Click on the license information
– Press the ‘Deactivate’ button in the license dialog that appeared
– Press the ‘Authorize’ button
– Put in your credentials and make sure to select ‘Machine’ when asked for the variant

You can also convert your license to iLok by going to your account page and click on the ‘Convert to iLok’ button.
