BTS expansion

[amishdemon]

I owned Civ 4 retail but when we switched computers I lost the disks because I only used BTS. I bought Civ 4 on steam yesterday and i was wondering how i install the BTS retail version with my steam version of civ 4. (can even do this?)

You cannot do this as far as I know. The executable for the Steam version and retail versions are different.

If it was the other way around, you might have been ok (BTS on Steam). They changed it a while back so that you had to own Civ4 on steam to buy BTS but I bought BTS before the changed it so I have it standalone essentially.
