Activation means creation of the license file (.irl) with the help of the purchased activation key. After purchasing the license you receive the key which you will assign to the control panel (until the key is not assigned the control device is not defined).
This procedure is performed in the MY ACCOUNT section of the web site. All purchased keys should be added in the MY ACCOUNT section and then assigned to particular devices with the help of HWID/Serial Number.
The ready license file should be added in Transfer and uploaded to the control panel together with the visualization project. You can find more detailed information about the activation procedure here.
