2.1. Answer:

Hi,

Thank you for reaching out.

Can you confirm this is Revit and not Revit LT?

If it's indeed Revit, the Lumion tab should appear automatically after installing the plugin and starting Revit.

Please try the following:

1. Please close Revit and uninstall the Livesync for Revit plugin again using the instructions in the article below:

• Knowledge Base: Download Lumion LiveSync for Revit

2. Restart your PC. Then download the Livesync for Revit plugin again and install it. Make sure your Windows User Account has administrator rights. Then launch Revit as an administrator.

Is the Lumion tab still not appearing in Revit?

If that's not working for you, try following this troubleshooting Article by Autodesk:
