I know of one Windows 95/DOS game that won't work in XP unless you disable sound. To do that you have to right click on the .exe and hit properties. Find the field that says CMD Line: "C:\Program Files\Yourgame\game.exe" and add a /n after the quotation marks. No idea if that works or not, but it's worth a shot.

It should look like this:
Cmd line: "C:\Program Files\Yourgame\game.exe" /n


EDIT: Nevermind, here (from wikipedia)

Changes to the Microsoft operating system introduced with Windows XP technology did not allow DLR to run. UBI could not locate this problem even up to 2002 and no support was offered on this issue. Fans however have targeted the problem. The cursor controlling software jams the programs operation. To fix this issue, right-click the desktop or start menu shortcut, go to properties dialogue box from the menu that appears, and change the target to "c:\(your Darklords folder)\darklord.exe" /WINCURSOR. This will replace the problematic color cursors with functional, black and white ones.
