Yes. Each of your plugin purchases comes with two activations, so you can use our plugins on multiple computers (both Windows and Mac), as long as you are the one using them. This means you can use the plugins in your studio and your live setup etc.
When using our online activation flow you can also deactivate your devices, so you should never run out of activations.
When using our offline activation flow you cannot deactivate your devices again. Should you need more than your two activations please contact support.
