License can be removed selecting it and clicking Shift+Del, although the activation counter is not decremented. For security reasons, each license can be activated by default 5 times, but if you exhaust the maximum number of activations or the counter is running low, please write us and we will reset it.
You are allowed to install a license at home or laptop (in this case, at your studio), provided that both copies are not used simultaneously. Many users make this request to us, so although this issue is not covered in our license agreement, we are flexible about it.
