I have tried do download a demo of MAX MSP from the website, but I cant install it. When I select the harddrive I would like to use, I get told that a version already exist. I am 100% sure that the program is not on my computer, but maybe the previous owner of my computer have had the software installed but the deleted it in the wrong way (throwing it in the thrash instead of uninstalling it properly). I have tried to search my computer for related files but can't find any. Have you got an idea where to find these? I use mac OS 10.6
