Problems installing system software
This section helps you solve problems you might encounter while installing
System 7.5 or greater and related software.
Not enough m emory to use the Installer
When you try to use the Installer, you see a message that the Installer is out of
memory. Usually this means that your disk cache or RAM Disk is set too high.
• Quit all open application programs. O pen the Memory control panel, set
your disk cache to the lowest possible setting and turn on Virtual Memory.
Not enough m emory to install the software
When you try to use the Installer, you see a message that your computer doesn’
t
have enough memory to install the software. This means that your Macintosh has
less RAM (random-access memory) than is required to use System 7.5 or greater.
• Contact your reseller for information on purchasing additional memory.
Not enough disk space
When you try to use the Installer, you see a message that there is not enough
disk space available to install the software.
• Make more space available on your hard disk by removing some files from
the disk. Make backup copies o f the files, if necessary, and then drag them
to the Trash and choose Empty Trash from the Special menu.
• If you are installing from floppy disks, you can also try starting up your
Macintosh using the Install Me First disk. Using the Installer this way
requires less disk space.
Difficulty modifying the System file
When you try to use the Installer, you see a message that the System file cannot
be modified (or repeated messages asking if it’
s okay to modify the System file).
• If virus-protection software is turned on, turn it off by dragging it out of the
System Folder and restarting your computer. Turn it back on after installation.
