Alcohol 120% Question

[skyman43]

I recently made a copy MOHAA and the expansion SPEARHEAD using Alcohol 120%. I installed both games to one of my computers using the copies.None of the original games were ever installed on the computer.Both games work fine until I try installing them on my other computer which then tells me to insert the correct CD when it comes time to play the game.Does Alcohol 120% have to be installed on both computers,or am I doing something wrong?I have a Lite-On 52x24x52 CDRW writer.
