If you have "Civ3:Complete" (Scholastic could have marketed it as something else tho) which is the product that Atari sold that includes all three versions, no patching is required. In fact, patching it will produce exactly the error you had because of the differences in the .exe files, and the different CDs. Now, why it wasn't made compatible with the older versions I don't know.
So do this...start the game. If on the menu screen you see "1.22" in the bottom left corner no patching is required, as that is the last patch level. I'm suspecting that you will see this, as most, if not all, of the Complete editions shipped at the 1.22 patch level.
