Try to install Realtek HD Audio driver from the link I gave, using another browser if your current one is giving an error.
Install that Realtek storage link.
Delete this folder: C:\Program Files (x86)\FreeRide Games
Then open Regedit. Find the subkey for that driver at the following location and delete it. Reboot:
