First off, I am trying to install a game that i bought on a whim for $10 and stumbled into many problems on my powerbook g4, 10.4.11. I mainly use this computer for Quickbooks data entry and for Internet, so for a couple of years that is all it has had to perform. Basically the application i'm trying to install is on a disk, and when i click on the .pkg file the screen blinks like it's trying to open the file, but never does. I've also tried dragging the file to my desktop. I've been searching this forum to find a solution. The best i can come up with has something to do with 1)disk utility, 2)software update, 3) Repair something, blah, blah. My disk utility file won't open. Software update unable to open. Tried re-booting with the install discs that came with the computer and ran the repair program, and it said it had found no problems. If there is any solution to getting the program installed, i would greatly appreciate the help, and it anyone has any ideas why my computer is acting like this that would be nice, too! Thanks in advance Also, i only can find 2 of my install disks, is there more i might want to search for?
