Dungeon Keeper 2/Getting Started
 Technical issues
Dungeon Keeper 2 has some compatability issues with Windows Vista. To avoid them, right click on DKII.exe or the Dungeon Keeper 2 shortcut, and choose properties. On the compatibility tab, make sure that it is running in Windows XP compatibility mode.
On modern systems, Dungeon Keeper may experience reduced performance during full-motion video or within the main menu - neither of these affect gameplay.
