According to NI I am allowed two parallel installations of NI players. I want to use Allegro to access GPO Studio since it is the only path available from this program. Unfortunately Studio is no longer functional with the advent of KP-2. So I bought a second computer with the thought of installing GPO and JABB in the old KP-1 format. I had installed GPO and JABB on my laptop and now wish to remove them and install both on the new computer in the old format. Bad choice!! NI no longer lets me de-activate the laptop installation. Hey guys, I used to think that changing the rules in the middle of the game was not appropriate. I think I'm never going to buy another program that uses NI players. Caveat Emptor.
