1. When does Lumion release the License Key?

Lumion will release the License Key when you click on the Quit button - provided that it is allowed to access the internet on the computer.

2. How can you release a License Key that is 'stuck' on a computer?

You should normally be able to release the License Key yourself:

2.1: Simply start Lumion on the PC that it is 'stuck' on, and then close Lumion.

2.2: Restart Lumion again to see if the License Key is released.

2.3: If not, please follow the instructions in section 3 below.

3. What do you do if you can't release the License Key yourself? 

• We can release your License Key at the Lumion Support Center between Monday and Friday.
• Please do not provide your License Key number in Lumion Support Center topics.
• Do not send a private message or email as the member of staff may not be available.
