I have two questions–one that I believe was answered in another location. First, I have Mac 10.4.1. The initial message when I tried to install software was that it would only work in 10.5. Do I need to upgrade. Second: I opened up the installer, but cannot find the program anywhere. Where is it installed? I thought that it would be on the desktop like the other related program is. Please advise. Also, for some reason, I have multiple copies of the installer. I presume I should delete them, but I would like to know where the program is installed.
