I have tried installing the game using a CD and it gets to where it is transfering files when it says, "Error:-1627 ERROR_FUNCTION_FAILED". After I push "ok" it says it needs to close and then does so.
Research on 1627 errors has come up with nothing, except that it has problems with the OS. This problem can be solved with Call of Duty 4 on Wine by following these instructions

I am not sure how to do that with Crossover Games, so I hope this helps the ninjas or whoever with all that programing.
