If your version is retail, this is a known issue as the game has the SafeDisc copy protection system, which had its driver removed from Windows 10. Other than obtaining an... executable..., your best shot is buying the game digitally on GOG, Steam or Origin, where it doesn't suffer from this problem.
If your game is indeed digital (bought on GOG, Steam or Origin), then this can be due to something else. Go to your computer's Control Panel (not Settings), go to Programs and Features -> Turn Windows features on and Off. Open the Legacy Components section and tick DirectPlay.
