Apple Macintosh Performa 570 series - Manual (Page 68)

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 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,
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 your System Folder. Most of the files in your
System Folder are used by your computer for internal purposes and are not
intended to be opened.
m Rebuild your 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.
m If the document is from a DOS computer, use the PC Exchange control
panel to specify which Macintosh program will open the document. For
information about working with DOS documents on your Macintosh, see
the “Using DOS Files & Disks” topic of Macintosh Guide, available in the
Guide (h) menu.
