Here's one, and it won't cost you a penny nor will you have to
spend 3 years learning to use the programs:

Office (word, excel, etc) does not come on the Win98 install
disc anyway, it comes on the MS Office install disc. If she HAS
to have Word (etc.) - some people do - you can find a copy on
eBay or at a garage sale.

Reinstall the MS Office programs from the Office CD, they arent on the
windows cd

Is it possible that just the desktop shortcuts are gone?

Try restoring the registry to a time before the problem.
Reboot to DOS and at the command prompt type the below and press Enter:

scanreg /restore  **Note the space after scanreg.

 Select a date prior to the problem and follow the prompts.

1.  MS Office apps are on the MS Office CD:  so if
you need to reinstal you need that CD, not the
Win98 system CD.

2.  You can try turning back the clock in case this
restores the MS Office apps you want.  Reboot
into MS-DOS (not Windows) and go via CD to
C:\Windows\Command
then key in
SCANREG /RESTORE
and select a date when the PC was working well.

3.  Find out whether you have really lost these apps
or only the shortcuts (LNK files) that load them from
the desktop.  The EXEcutable files are
EXCEL.EXE
WINWORD.EXE
OUTLOOK.EXE
and so on.  You can go via My Computer to
C:\Program Files\Microsoft Office\Office
and double click on each EXE in turn, to verify
whether it will still run OK.

4.  Components of MS Office are large and elaborate
for business purposes (fancy printing etc.)   Most of
their features are not needed for everyday non-business
use.   You may find other free software (e.g. Star Office)
does all you require:  most can read files in MS formats
and some of them write in MS format as well.

She do not need to have disk for Windows 98
But she needs disk for office because Word, excel are office applications
