I have the old original version from game jackal. today i want to make the update on the pro version. When i want to make the installation it comes the message:"setup has detected that Game Jackal is currently running - please close all instances of it now...." But the program isnt running at all...so how can i make the installation, have i to uninstall the old version...? another question is: are the old programs still running with the new version, when it is installed??
