Err Msg After Running BUSETUP.EXE: Wrong DBLSPACE.BIN Version (114362)

The information in this article applies to:
    Microsoft MS-DOS operating system 6.21
    Microsoft MS-DOS operating system 6.22

This article was previously published under Q114362


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.

When you have an MS-DOS 6 DoubleSpace-compressed C drive and you install MS-DOS 6.21 Upgrade, Setup installs the MS-DOS files on the host drive for C. As a result, you receive the following error message when you restart your computer after MS-DOS 6.21 is installed:

wrong dblspace.bin version
When this occurs, your compressed drive is left unmounted.


This problem occurs when you boot your computer from the MS-DOS 6.21 Upgrade Disk 1, exit Setup (BUSETUP.EXE), and then try to run Setup (SETUP.EXE) from the A prompt.


To correct this problem:

    Uninstall MS-DOS 6.21 Upgrade.
    Boot your computer from drive C.
    Run MS-DOS 6.21 Upgrade Setup from Setup Disk 1.
