SU0168 Error
(Upgrading Over Win95/98)
I am trying to install
Windows 95a (or 98 or ME) over an earlier version of Windows. I am getting an
"SU0168" error message that says I already have
an operating system.
This article
discusses upgrading from Windows 95/95a/98 to a later version
of Windows (but not from Windows 95 or 95a to Windows 95b).
If you are upgrading from
Windows 95 or 95a to Windows 95b (OSR2) go to:

It is very important that
you read this article!
If you are upgrading from
Windows 3.1x to Windows 95 or 98 or ME,

You've
probably acquired a "full" or "OEM"
Windows distribution. Unlike the "upgrade"
release usually sold in retail outlets, this version is
designed not to upgrade an existing Windows
installation. However, it is possible to
"fool" the setup program into performing an
upgrade. There are at least four techniques purported to
accomplish this. I've summarized them below. Click on the
links to obtain the full description.
Note!
Based on user feedback, method #3
works best. Method #4
also works and is handy under special circumstances. Unless you are
just curious, don't bother trying the other techniques.
Method #1:
Not Recommended |
This technique involves
launching Windows setup from within the current version of Windows, interrupting installation after the dialog
that generates the "SU0168" error,
editing one of the temporary configuration files
and then restarting the process. |
Method #2:
Not Recommended |
This
approach is similar to method #1, but interrupts setup at a different point. |
Method #3:
Best! |
This is by
far the simplest approach and is the one most likely to succeed. It
avoids the "SU0168" error message by
renaming certain Windows files. |
Method #4:
Slick! |
This is
similar to method #3. You don't need to rename
any files but do need a "Startup Disk" for the version
of windows to which you are upgrading. |
