Heh, I think I can help. ‘Echo Off’ is not an error, it’s a DOS way of stopping command line instructions repeating. So a program doesn’t ‘double load’ or something, I guess.
ANyways. The KQ Collection installer is buggy, I think. Just copy the folders themselves from your CD’s. They’re preinstalled, so you don’t need to do anything except run install.exe and select your music/audio equipment.
