A license is required to render Forest objects, although you don't need to edit them. This rule applies when Max runs on interactive mode (opened by an human operator), but not for unattended render modes, as Backburner.
So in this case i suggest you activate the license in the laptop, if you are going to use it as main workstation.
To delete a license from a workstation, just select it in the License Manager and click Shift+Del. But note that this procedure doesn't modify the activation counter, only deletes the license.
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 add more activations.
