Hi BMcC, Lumion Demo 5.3
which is available via the 'Try' link
at the top of this page.
If you can confirm that this is where you got the Download Manager
from (after filling in the form and clicking on the link in the email that was sent to you), you can safely ignore the warning in Norton. The Lumion Demo 5.3 Download Manager
and installer from lumion3d.com are 100% safe.
