Archive Utility launches, compresses the item (s), and then it quits. If you want to compress a file, a folder, or a group of items, select it/them, then right click and choose Compress. I've followed the directions: downloaded because i use a 32 bit windows, downloaded the install_addon m-file and created an m-file for it, made sure the two files were in the current folder, and ran the install_addon command.
I'm having difficulty completing the installation process of the simmechanics link addon.
