You have just installed a free 14-day Lumion Trial.
When you run it, it is saying that the Trial period has already expired even though you have not used it before.
How can you get one that is not expired:
Have you already run a Lumion 12.x Trial previously on your PC?
And have you again applied for a new Trial License Key?
If so, then it is only possible to run a Lumion 12.x Trial once per major version on a given PC from the date the License Key was first activated.
The only way to test Lumion on this PC is to apply for a different type of Trial version, i.e. the full, unlimited Lumion Business Trial (Pro Trial):
- Knowledge Base: Is there a Trial version of Lumion?
- Knowledge Base: What does the error message 'Your License Key has expired' mean?
