Well... this may work unless you already saw these from various threads.
Set your desktop to 256 colors and Win98/Win95 compatibility before starting the game.
"When you launch the Setup.exe, it will ask you for a system check - click No. The Setup continues and the error will not appear."

From Dan D on Win7:
"install game,
right-click game icon, click "property", click "compatibility" and there you:
1) click "windows 95 compatibility mode" and
2) click "265 colors",
3) save changes."
Ignore the error message "sound related error" if it pops up and don't use the voice recognition while you are playing the game, that makes the game crash.
