Symptom
Printer software will not install. You may see alert boxes with messages similar to the following:
"There is not enough memory to use the Installer."
"There is not enough disk space to use the Installer."
"The file system cannot be modified."
"The item <name> cannot be replaced."
Solution
Software version and compatibility
Be sure that the printer is compatible with the version of Mac OS 9 that you are using. Check the printer manufacturer's Web site for later versions of the printer drivers than those included in the box with the printer. If later versions exist, it is normally best to use them instead of the ones included in the box. Some printers may also require firmware updates that would be available at the manufacturer's Web site.
Check for instructions, "Read Me" file
Be sure to follow the installation instructions included with the software. If using a later version that you downloaded, be aware that any "Read Me" file included with the download may supersede what was included in the printer box.
Turn off security software during installation
Depending on what kind of security and virus-protection you use, you may need to turn it off while you install software. Even if your security software allows per-incident installation authorization, you may still need to turn it off to eliminate the possibility that it is interfering.
Isolate hardware
Isolate the computer hardware to eliminate the possibility that another device is interfering. Disconnect all peripherals and third-party hardware. Use only the Apple keyboard and mouse included with the computer.
Check for extension conflict
To check for an extension conflict, open the Extensions Manager control panel and select the Mac OS 9 Base set, then restart the computer. Try installing the software again. Afterward, you need to reopen the Extensions Manager and go back to the set you were using before (most likely "My Settings"). See technical document 30929, "
Mac OS: Extension Conflict Troubleshooting/Extensions Manager Features".
Check the installation CD
If installing from CD, make sure the disc is not dirty or scratched. Clean the data side of the disc by using a dry, lint-free cloth to gently wipe the CD from the spindle hole to the outer edge. Do not wipe in a circular fashion. If you have a CD-ROM lens cleaner disc, use that to clean the drive.
Record alert messages for reference
If you see an alert box with a message during installation that is not discussed below, write down the message for reference when seeking technical support.
"Not enough memory to use the Installer"
If you are trying to use an installer that is on your hard disk and see the message "There is not enough memory to use the Installer," make sure the computer is started up from the hard disk, and it is the selected volume selected as the destination disk when installing.
"Note enough disk space"
If you see a message that "There is not enough disk space," make more space available on your hard disk by deleting some files from the disk. Copy the files you want to keep to another disk, then drag them to the Trash and choose Empty Trash from the Special menu to delete the files.
"File system cannot be modified"
If you see a message that "The file system cannot be modified" or "Installation was not successful," make sure any security and virus-protection software is turned off.
"The item cannot be replaced"
If you see a message that "The item <name> cannot be replaced," the installer is attempting to replace a file, but there is a folder on the disk that has the same name as the file being replaced. (Files cannot replace folders.) Find the folder on your disk and rename it, then try the installation again.
Clean installation
If nothing else has resolves your issue, perform a clean installation of Mac OS 9. If you are installing from a Mac OS 9 CD that did not come with your computer, the version number printed on the disc (such as 9.0.4) must be later than the version of Mac OS that was originally included with your computer. To learn about clean installation, see technical document 58176, "
Mac OS 8, Mac OS 9: Performing a Clean Installation".
