Hi ddschneider1972, welcome to the
Lumion Support Center, and thanks for forwarding the email with the link to the
Download Manager for
Lumion 5.3 Demo!

I have tried opening the link in
Internet Explorer 11, Edge, FireFox and
Chrome, and the Lumion
Download Manager is being downloaded in all of the internet browsers.
This means that there's something on your PC which is preventing your internet browsers from saving the
Download Manager executable file (.exe) on your harddrive.
Does it work if you temporarily turn your anti-virus software off before clicking on the link to the
Download Manager in the email?
By the way, I should mention that
Lumion 5.3 Demo is about 2 years old, so you might want to consider asking your local reseller to send you a link to the 7-day
Trial version of
Lumion 7.0.1 Pro. There's more information in
this Knowledge Base article.
