Hi,

 

Thank you for reaching out.

 

Sorry to hear you are having trouble starting Lumion.

 

It looks like there may have been a problem with the installation. Something on the PC likely removed important installation files which prevents Lumion from starting correctly. From our experience, this 'something' is usually overzealous security software on the PC.

 

Our recommendation would be to:

 

1. Uninstall Lumion 2024 completely.

 

2. Delete all the .00 Lumion installation files (which should be in your Downloads folder).

 

3. Add Antivirus and Firewall exclusions for the Lumion Installer (Lumion_2024_2_1_Download.exe). Here's how to do it:

 

 

In case you are using a different Antivirus software, the steps should be similar and easy to look up.

 

4. Run the Installer as an administrator to download and install Lumion again. Then run Lumion as an administrator.

 

Let us know if the issue persists after trying the above.

 

Thanks in advance and apologies for the inconvenience.
