Why does Lumion require sign in to start?

Beginning with version 2025.1, all users will be required to log in with a Lumion Account when launching Lumion for the first time. That includes those using a Studio (Floating) or Faculty (Floating) License Key.

If you are already using a Named-User license or a Trial, the way you access Lumion does not change, and you likely already have an Account.

If not, don't worry, it's a quick and easy process. See this article for more information on how to set up and use your Lumion Account:

Note: Users who have installed or activated Lumion with a Studio License Key do not need to have the license Registered on or assigned to their Lumion Account. All they need is the Account itself for access.

Why This Change?

This step is essential for accessing Lumion Cloud, our new visual project collaboration platform.

Lumion Cloud lets you upload and share renders, get feedback, and manage approvals in one centralized space. Your Lumion Account is what connects you to that experience, securely and seamlessly.

We're also future-proofing Lumion by unifying how users access our tools. Logging in makes it easier for us to support new features, customization options, and integrations moving forward.

2. Try clearing the browser's cache, function key F5, or Ctrl + F5. You can access this setting in your browser by pressing Ctrl + Shift + Delete.

3. Try setting a different browser as the default one via Windows settings. Here's how to do that:
