Technical information

An application program won’t open.
m The application program may already be open. Check the Application menu to see which
applications are running.
m There may not be enough memory available to open the application. Quit any applications you’re
not using and try again. If that doesn’t work, try restarting the computer.
m If the application is on a floppy disk, make sure the disk is unlocked. (You unlock a disk by sliding
the tab at the corner of the disk so that it covers the hole.)
m The application may be damaged, or it may not be compatible with PowerPC technology. Check to
make sure the software is PowerPC compatible, and install it from a known good source (such as the
application’s original disks).
m Check that the application is compatible with the version of system software that you are using. (See
the application’s documentation, or contact the manufacturer of the application or the place where
you bought it.)

m Try starting an application that you think might be able to open the document. Then choose Open
from the application’s File menu to open the document. For more information, see the
documentation that came with the application.
