so i bought my scratch pro years ago 2009 if I'm correct I'm trying to use it again in my computer but I don't have the installer disc and it seems that I can't find it anywhere obviously I have my license from that scratch pro so the question is can I use it with another software since everything is updated now .?? I also try to download old files like scratch pro 1.1.1 in my mac but it's said that it cannot be installed in my mac any recommendations?
