Hi,
Since the issue is possibly caused by some damaged Windows Store components, we recommend resetting Windows Store and see if it helps. Follow the steps below:
- Open Settings.
- Click Apps, then Apps & features in the left pane.
- Locate Store, then click Advanced options.
- Click Reset.
- Restart your computer.
Also, we recommend temporarily disabling your Norton antivirus when trying to install FH3.
Update us on the outcome so we can provide further assistance.
