Installing and playing on Windows Vista
The following Blizzard titles should install and run on the Windows Vista operating system:
StarCraft
StarCraft: Brood War
Diablo II
Diablo II: Lord of Destruction
Warcraft III: Reign of Chaos
Warcraft III: The Frozen Throne
After installing, we would strongly recommend downloading and manually installing the latest patch for the game, before attempting to play. You can find the latest patch for these titles here. To install the patch, simply double-click the file after downloading it to your computer. Once you have patched your game, any messages stating that ‘This program has known compatibility issues' can normally be ignored (by ticking ‘Don't show this message again').
As Windows Vista is still a fairly recent operating system, we would also recommend that you have the latest drivers installed for your hardware.
If you continue to experience problems we will endeavour to assist you in getting the game running, feel free in contacting us if you require further help.
