Title: [Awaiting Reply] Red "Success" at startup then nothing happens
Post by: IMDesigns on May 28, 2018, 10:19:11 pm
I just downloaded and installed Lumion 7.5 trial version. It seems to have installed correctly as the programs starts. However, after the splash, there is red text that reads "SUCCESS" and then nothing happens.

My system specs:
Windows 10 Pro Version 1709 Build 16299.431
Intel i7-8700K OC @ 4.70 GHz
16 GB RAM @ 3200 MHz
MSI GeForce GTX 970 4GB Gaming Graphics Card

Thank you in advance for your help.

Hi IMDesigns

Welcome, and thanks for your interest in Lumion by downloading the (public) 7 Day Trial.  Are you aware there is also a Pro Trial available, see our Knowledge Base Article: Is there a Trial version of Lumion? (

Now, about the issue, the message "success" indicates that when starting Lumion, it is having difficulty contacting the license server to verify the license.  There are some possible reasons why that might happen.  Usually it is from some firewall setting or over-zealous anti-virus or monitoring software.

To get under way:
1. Please click on this link ( Does it say "The license server is running" or "LOGINFAILED"?

2. Also, forward the email from Act-3D titled "Getting Started with Lumion" with the license number, activation code and download manager link to us at [email protected], so we can try to install your version at another location.

3. Please zip + send the 'hosts' file from "C:\Windows\System32\drivers\etc" to [email protected] Thanks in advance.

4. Does it work if you temporarily turn on Windows Defender and then temporarily turn off your 3rd party firewall/anti-virus software before running Lumion?
