Thanks, I just figured it out. Like I said, I installed the second copy from scratch into another directory. I can run the first one without problems...however, the only way I got the second copy to work was by loading the "Patcher Setup" file in the second AoC directory. I managed to run both instances on one comp in windowed mode. At medium settings it is actually decent FPS (30-45). Thanks for your software - I was hesitant to use it (oh noes - learning something new to use) but it was pretty easy. You had a warning in your sample that stated that it can't send the keystrokes to a background window...the noob that I am...I thought that meant that you can't really utilize the program the way I did with AHK...but it works the same way...just that once I activate the script in AoC1 - it permanently jumps to AoC2 as the active window.
