1. Here's how to resolve the most common problems

If the Download Manager does not start downloading Lumion, gets stuck or displays an error message (for example "Access denied"), please go through the following checklist:

1.1: Please move the Download Manager to the Desktop before running it. Do not run it on a network drive or in a cloud back-up folder such as OneDrive, GDrive or DropBox.

1.2: Make sure that you have administrator privileges when you run the Download Manager (Right-click on the Download Manager and select Run as Administrator):

1.3: Make sure you have at least 20 GB free disk space on the drive you are downloading Lumion to.

1.4: If the Download Manager requests an Activation Code when you start it, please double check that you have only copied the characters in the Activation Code from the Getting started with Lumion email, and not any spaces or other characters:

1.5: Please make sure that your firewall, router, anti-virus and security software are not preventing the Download Manager from accessing the following domains via port 80 (HTTP):

• product-download-storage.lumion3d.net
• downloadmanager.lumion3d.net

1.6: Please make sure that your anti-virus or security software is not preventing the Download Manager from creating a Lumion_VERSION folder in this location:

• C:\Users\USERNAME\AppData\Local\Lumion_VERSION

1.7: Please make sure that your anti-virus or security software is not preventing the Download Manager from downloading temporary .BINPART files to this folder:

• C:\Users\USERNAME\AppData\Local\Lumion_VERSION

1.8: Make sure that the Download Manager is allowed to write to the directory it is located in.

1.9: Run the Download Manager using Run As Administrator (in Windows Explorer: select the Download Manager exe file, right-click -> Run As Administrator).

2. What if that does not resolve the problem?

If it still isn't working it means that the security settings on your computer and/or network are so strict that the Download Manager can't complete the operation.

2.1: If so, we recommend that you download the installation files on a network with less restrictive security settings (for example at home), and then transfer the installation files to your office.
