Installing Eagle Watch

I bought Rainbow Six Eagle watch at a garage sale just for the heck of it and when I tried to install it it said Rainbow Six not installed, but nowhere on the box did it say expansion pack for rainbow six I thought it was just another installment of the series, so is there anyway to make it think rainbow six is installed or just bypass that part.

 

Does No One know how to do this

 

If it is an expansion, and not a standalone game, then it most likely will not work at all unless you install Rainbow Six, as the original game installation will have files that the expansion will require. Look around the publisher's website to see if it is indeed an expansion, and if it is, either try to return the game to the person you bought it from, or go buy Rainbow Six.

 

Well that sucks, They should put It on the Box!

 

I've no doubt it is somewhere on the box.
