possible errors and how can avoid or fix the problems causing these errors. If you

setup hangs later in the installation.
Setup Error Messages
that an earlier version of SetupX.dll or NetDi.dll is in use:
There are open applications during installation. Either choose the option to replace

create files on your startup drive and cannot set up Windows 98. There may be too many
files in the root directory of your startup drive, or your startup drive letter may have
been remapped (SU0018):
The root folder of a drive holds a maximum of 512 files and/or folders. You'll have to

Install Windows 98 from DOS.
Not enough conventional memory to continue the installation. Comment out
lines in CONFIG.SYS and AUTOEXEC.BAT one-by-one until you have enough memory to continue.
This will not load the TSRs and free up conventional memory.
Delete any unnecessary files or try the clean-install method to format the hard
drive and start from scratch.
Write to the Temporary Directory:
There is not enough room in the temp directory. Clear all the files out of
C:\WINDOWS\TEMP (or the temp directory specified in AUTOEXEC.BAT by the line
TEMP=...) If you have space on another drive, use the following command to change
the temporary directory location: SETUP /T:<drive letter>:\TEMP
CAB File Error
One of the following conditions has probably occurred: PC infected with a virus,
low conventional memory, bad media, or hardware, especially CD-ROM drives. Try the
clean-install method for setup. This method will eliminate problems caused by a
virus or low conventional memory. If you have a bad CD or CD-ROM drive, you'll
probably have to have it cleaned or replaced, but in the meantime you can try to copy the
cab files to the hard disk and run setup from there.

EMM386.exe, QEMM, or 386Max) from your CONFIG.SYS file, and then run Setup again.
Not Back Up Your System Files:
Your hard drive does not have enough free space to back up the system files.
Remove any unneeded files. NOTE: Uninstall can require up to 75 MB. If
Setup is not offering you the choice of saving your system files, you may be very low on
free disk space.

A file or folder called DESKTOP exists on your computer. Rename or move your
current DESKTOP folder, and then run Setup again.
Setup cannot open a required file, possibly because the file is missing or damaged, or
because your computer does not have enough memory. Try installing Windows 98 from

SU99 is a prefix that is added to all errors that Setup does not have a specific
error message for. These errors are often caused by low conventional memory. Try
installing Windows 98 from DOS.
Setup does not
have enough conventional memory to check your computer's hard disks. or Setup
could not check the hard drives on your computer.:
If you receive either of these errors, Setup was unable to run SCANDISK to check
your hard drives. This could be because of low conventional memory or your disk contains
errors that SCANDISK cannot fix when run from Setup. Since the setup process only
runs SCANDISK with minimal options, you should reboot to DOS and run SCANDISK /ALL.
This will use all SCANDISK options to fix the problem. If you still have problems
after this, SCANDISK /ALL /SURFACE. This will take a lot longer, but it will check
the actual physical media of the hard drive to ensure your hard disk is in good shape. If,
after running SCANDISK with these options, Setup still won't continue, you should run
SETUP /IS to bypass SCANDISK. NOTE: Bypassing SCANDISK is not recommended and should only
be used if you are positive your disk(s) contain no errors. If there are still errors,
Setup may fail and your system may no longer boot.
