SYMPTOMS
When you run MS-DOS SETUP or SETUP /E, Setup may display the following
error message:
Unrecoverable Error
Error renaming old utilities.
Press ENTER to exit Setup.
CAUSE
This error occurs when:
• The path has been set with the SET PATH= command, the drive
letter of the DOS directory is in lowercase (for example, SET
PATH=c:\), and you are running SETUP with the /E parameter.
-or-
• There are no directories in the path that contain MS-DOS files and
there is a file in the root called "DOS."
WORKAROUND
The Path Has Been Set with SET PATH=
This is a known problem with MS-DOS 6.x Setup. SETUP /E checks the current
path to locate the MS-DOS directory. If the MS-DOS directory is in
lowercase letters, Setup displays the unrecoverable error message listed
above.
To correct this problem, use the following steps:
• Press ENTER to quit Setup.
• Type path at the MS-DOS command
prompt and press ENTER. This displays the current path (for example,
PATH=c:\dos;c:\windows;c:\utility).
• Use the PATH command to reenter the path in uppercase letters. For
example, type the following at the MS-DOS command prompt and press
ENTER:
PATH C:\DOS;C:\WINDOWS;C:\UTILITY
• Run SETUP /E again.
A File Called "DOS" Is in the Root Directory
To allow Setup to continue, delete the "DOS" file. Setup creates a C:\DOS
directory and proceeds normally.
If there is no C:\DOS directory, the Setup program traverses the existing
path to find a directory with MS-DOS files in it. When it locates a
directory with any MS-DOS files, it assumes that this is the directory
containing the old MS-DOS files and continues with the setup.
If no directory in the path contains MS-DOS files and a file called "DOS"
exists on the root, the system configuration screen shows that a C:\DOS
directory exists. When you continue with the setup, the above message is
displayed.
STATUS
Microsoft has confirmed this to be a problem in MS-DOS versions 6.0, 6.2,
6.21, and 6.22. We are researching this problem and will post new
information here in the Microsoft Knowledge Base as it becomes available.
