Great older single and multiplayer game. Works with Windows 98 thru Windows 11. Some pc's need direct x 9c complete package installed. Make sure you make a desktop shortcut to the correct exe to fire the game up. It's the "Viper Racing.exe" inside the Sierra/Viper Racing folder, NOT the "race.exe" in the Sierra/Viper Racing/Data folder. In properties in the VR shortcut you may have to set the "compatibility" to XP service pack 2. Also some newer graphics cars will not play the game or will show messed up stuff while playing. Somebody in a forum mentioned something about getting "voodoo" and run the game with that. I never looked into it. Good luck!
