Good, but since you bought the game you can also legally download my version, from here: http://forum.ee2.eu/t1520-ee2-download-empire-earth-ii-empire-earth-ii-the-art-of-supremacy-for-freeI will download the game again from Gamer's Gate.
Yes, install only UP1.4 (you don't need UP1.3), but remember to install the patch to the right folder. Sometimes the installer doesn't detect automatically the right folder.Now since Gamer's Gate version is 1.2, that means I don't need to install 1.2 patch, correct?
After you install EE2 - click the right mouse button on icon "Launch Empire Earth II", and select: "Open file location" from the list. Then you'll know where the patch should be installed.

It doesn't matter where you save the installer file.I can run your patch through my Downloads folder because I ran the program after I moved it into the EEII folder which may have caused some issues.
