On one computer, but on other computers opening file works correctly.
When uploading and opening a file in Fusion Online.

Causes:

The file was saved or imported on another machine using a newer version of Fusion.
A Fusion update is required on the device.
Fusion was installed as Administrator.
The Fusion shortcut is referencing an older version.
The file was saved in a Fusion Insider Build version, which is an unreleased future version of Fusion.

Solution:

Update Fusion

Check for updates in Fusion and update to latest version.
Repair Fusion using the Service Utility. This should reinstall Fusion and push to the latest version.
Re-download Fusion. See How to download Fusion to install the latest version.

Remake the Fusion launch shortcut

Fusion may have been launched using a shortcut that leads to an older version of Fusion. Delete the current Fusion launch shortcut:
- MacOS: Right-click Fusion in the Dock > Hover over 'Options' > Select 'Remove from Dock'
- Windows: Right-click Fusion in the taskbar > Select 'Unpin from taskbar'
Open the Fusion Launcher shortcut (this should open the updated version of Fusion):
- Windows:
  1. Turn on hidden files and folders on Windows
  2. Go to the following folder: C:\Users\***\AppData\Local\Autodesk\webdeploy\production\<numerical folder>
  3. Open FusionLauncher.exe.
- macOS:
  1. Access the hidden Library folder on macOS
  2. Go to the following folder: Library\Application Support\Autodesk\webdeploy\production
  3. Open Fusion360.app.
With Fusion open, pin the new shortcut:
- MacOS: Right-click Fusion in the Dock > Hover over 'Options' > Select 'Keep in Dock'.
- Windows: Right-click Fusion in the taskbar > Select 'Pin to taskbar'.

Fusion Insider

This warning can occur if the file was saved on an Insider build. If taking part in the Fusion Insider program, ensure that all team members are participating in the Insider program and are opening the file on the latest Fusion Insider build.

Open an older version of the Design

If it's not possible to install an updated version of Fusion, you can promote a previous version of the design. See How to open a previously saved version of a Fusion design.
