I can't offer any assistance but... I'm a little confused by this... World of Warcraft II? That doesn't exist. Do you mean Warcraft II? (quite an old RTS... Windows 98 I think) or one of the World of Warcraft expansions (Burning Crusade, Wrath of the Liche King, Cataclysm... they will need the original game to run).
I'm guessing that it is Warcraft II. A very different game to World of Warcraft, which, as a spinnoff, has pretty much eclipsed its parent. So if your not a gamer I can understand the confusion. You wouldn't be the first (I have personaly met others).
May be a good idea to clarify what the game is so that people with more software knowledge than myself help you. I just know games
I do know that the age difference between the games is substantial and the likely issues are different.
