Yes you can!
Octane licenses are designed to be automatically deactivated on exit, ready to be instantly activated on another machine.
You need to visit your personal Octanelive page, here:
[for Commercial licenses](
https://render.otoy.com/account/octanelive.php)
[for Subscription licenses](
https://render.otoy.com/account/subscriptions.php)
If the licenses are listed in green as Available, you can activate the licenses on another machine.
But sometimes, there could be an issue during deactivation, due to system update , or a crash, or an issue with internet connection.
If they are listed in blue as Active, you need to deactivate your licenses by pressing the red Unlock button beside of both licenses, Standalone and Plugins.
