Apple Macintosh LC 630 DOS - Manual (Page 101)

You see a message that an application program can’t be found.
The following dialog box appears if you try to open a document that was
created with software that is not on your hard disk.
Normally, you see this message if you try to open a document that came from
another Macintosh with software that is different from yours.
m The Macintosh Easy Open control panel is not installed. This is a control
panel that you can use to open documents when you don’t have the
program that created them. Reinstall the control panel from the system
software disks or CD-ROM disc containing system software that came with
your computer. (See the section “Installing or Reinstalling Mac OS System
Software” later in this chapter for instructions.) See Appendix D for
instructions on using Macintosh Easy Open.
m Some documents can be opened by more than one application program.
Try starting a program that you think might be able to open the document,
and then choose Open from the program’s File menu to try to open the
document.
m Purchase and install the correct software to use the document, or find out
if the creator of the document can convert it to a form that one of your
programs can use.
m Don’t try to open the files in the System Folder. Most of the files in the
System Folder are used by your computer for internal purposes and are not
intended to be opened.
m Rebuild the desktop by holding down the Option and x keys while starting
up your computer. Keep holding down the keys until you see a message
asking whether you want to rebuild the desktop. Click OK.
