There is no need to de-activate your license.
You can install Lumion on as many PCs as you want.
The Trial version is valid for a total of 7 days over a 30 day period from the date you received the 'Getting started with Lumion' email.
By the way, you might also want to consider getting 'Lumion 8.5 Pro Trial' as it's a newer version with more features.
