SkyGuard cannot be used without a valid license.

To register a license you must click the  button.

By default SkyGuard ask to register the license from a file, if you have a valid license file click "Yes", if you do not have a license file please send a license request, see Requesting a license

To register it, you must select the folder and the license file that you have received.

Once the license file is selected, click "Open" to register.

If the license is valid for the machine, SkyGuard will display the following message box

Click "OK" to continue.
