MS-DOS 6.2 Step-Up Error Message: Cannot Update File (106433)
The information in this article applies to:
• Microsoft MS-DOS operating system 6.2
• Microsoft MS-DOS operating system 6.22
This article was previously published under Q106433
This information applies to both Microsoft DoubleSpace and Microsoft
DriveSpace. For MS-DOS 6.22, use DRVSPACE in place of DBLSPACE for commands
and filenames.
SYMPTOMS
When MS-DOS 6.2 Step-Up is unable to update a file, the following
message is displayed:
Cannot Update File
Setup could not update the following file
to MS-DOS 6.2:
<filename>
Although Setup can continue without updating
this file, your MS-DOS 6.2 installation
will be incomplete.
For more information, see the README.NOW file,
which is located in the same drive and directory
as your Step-Up files.
To continue, press ENTER.
CAUSE
Setup displays this message when the listed file does not exactly
match the Microsoft MS-DOS 6.0 Upgrade version of the file.
MS-DOS 6.2 Step-Up uses binary patch files to patch the MS-DOS 6.0
files into the MS-DOS 6.2 version. Each binary patch file
<filename.xx#> contains a checksum for the original MS-DOS 6.0 file
and information on how to patch the file.
If the checksum for the file on the hard disk does not match the
checksum contained in the binary patch file, SETUP cannot patch the
file and displays the "Cannot Update File" message.
RESOLUTION
To work around this situation:
• Restore the MS-DOS 6.0 file by expanding it from one of the
original MS-DOS 6 Upgrade disks.
• Run MS-DOS 6.2 Step-Up again.
If there are a lot of files that can't be updated by MS-DOS 6.2
Step-Up, you might find it easier to reinstall the MS-DOS 6 Upgrade
and then run MS-DOS 6.2 Step-Up again. To do this:
• Confirm that the DEVICE=C:\DOS\SETVER.EXE command is in your
CONFIG.SYS file.
• Use SETVER to set the version number for SETUP.EXE to 4.00 by
typing the following at the MS-DOS command prompt and pressing
ENTER.
• Restart your computer so that the SETVER change takes effect.
• Run MS-DOS 6 Upgrade Setup.
• After MS-DOS 6 Setup completes, delete SETUP.EXE from the SETVER
table by typing the following at the MS-DOS command prompt and
pressing ENTER:
• Restart your computer so that the SETVER change takes effect.
• Run MS-DOS 6.2 Step-Up Setup.
If you have a version of MS-DOS 6.0 that was modified by an original
equipment manufacturer (OEM), MS-DOS 6.2 Step-Up cannot update the
MS-DOS 6.0 files. You must obtain an update from your OEM or purchase
the Microsoft MS-DOS 6.2 Upgrade.
NOTE: There is no way to expand or update the .xx# files manually.
