GSX activation, how and where?

[Queenofsky]

Hello

I did buy and downloaded GSX from the Link I get from Simmmarket. I have also 2 Acitvation key.
But where I can activate GSX?
It appear on P3Dv4 Menu: Add-ons, then GSX
But under the title GSX I have only:
Disable
Settings
Customize aircraft
Show GSX Menu by pressing You Control Ctrl.+Z (I did chanage that from Shit+Ctrl.+F12)

No other title for activation GSX!

Thank you for your help.

Kind Regards

You need to go through the Add-on Manager to do it.
