I'm trying to install Stuffit Expander 4.5 on my Macintosh Classic II. It says I need system 7.1 or higher to install the software. I tried to install system 7.5 on the machine, but the hard drive didn't have much room. If anyone has system 7.1 installer or updater's from system 7.0.1 to 7.1, tell me. Thank you.
