Hey Andre 54-

A big THANKS to you! I was having the same problem trying to install version 2.0 on my beige Mac G-3 using 8.6. I was getting the "corrupted file" Zip deal also attempting to install, so I went to "get info" as you suggested and upgraded the preferred memory from 384 to 900k and wham!.......the program installed as smooth as butter.........THANKS AGAIN! Hope this information helps others!
JM
