If you receive "FallGuys_client_game does not have a valid digital signature" alert, please verify the integrity of game files on Steam:
- Restart your computer and launch Steam.
- From the Library section, right-click on the game and select Properties from the menu.
- Select the Local files tab and click the "Verify integrity of game files" button.
- Steam will verify the game's files - this process may take several minutes.
If the above steps didn't help, please set your Norton Firewall to Allow Always for FallGuys_client_game.exe file only.
Note: Use that option only if the game was downloaded from Steam and is running from a folder you know is safe.
