A background program such as an antivirus application may be interfering with Fable 3.
Perform a clean startup of the computer (also known as a "clean boot"). To do this, view the following Microsoft Knowledge Base article:
331796 Perform a clean startup to determine whether background programs are interfering with your games or programs
When you start Microsoft Windows, other software may start automatically together with the operating system. These programs and services can include antivirus software and system utilities that may interfere with the game. When you perform a clean startup, you prevent these programs from starting automatically. You must be logged on as an administrator or as a member of the Administrators group to complete this procedure. If the computer is connected to a network, network policy settings may also prevent you from completing this procedure.
