Apple Power Macintosh 5200/75 LC - Manual (Page 64)

m The program requires special hardware, such as a floating-point unit
(FPU), and your computer doesn’t have the hardware installed.
Check the documentation that came with the program to find out if the
program requires a Macintosh with special hardware, such as an FPU. Then
check the Technical Information booklet that came with your Macintosh to
find out if your computer is equipped with such special hardware, or if the
hardware can be installed. Consult your Apple-authorized service provider
for information on installing special hardware in your computer.
You can’t open a document, or you see a message that an application program can’t
be found.
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.
