I am inclined to think - as Terence suggests - that it is just a space issue. You need 3Gb free to install, it is recommended that you always have 10% of your hard disk free anyway. Activity Monitor might show you how much hard disk is being used for virtual memory. It can be 3 to 6 Gb. So 2.4 Gb free is probably not enough. If you have an external hard disk, I would copy any important stuff to it using Carbon Copy Cloner or similar, then low-level format your internal hard disk and start the Tiger install from there. In my view, ALWAYS best to start with a clean disk, if you get a machine from elsewhere. keep us posted on your progress..... regards, Trevor
