MS-DOS 6.21 Err Msg: Setup Cannot Continue. Your Computer... (113601)

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

This article was previously published under Q113601


When you install MS-DOS 6.21 Upgrade over IBM PC-DOS version 6.1 (with data- compression installed), Setup displays the following error message:

Setup cannot continue. Your computer has DoubleSpace installed on it.
MS-DOS 6.21 does not support DoubleSpace.


With data compression installed, IBM PC-DOS 6.1 includes the files DBLSPACE.000, DBLSPACE.BIN, and DBLSPACE.INI in root directory of the host drive. As a result, Setup cannot install.


To work around this problem, remove the IBM compression by running SSUNCOMP.EXE and then run MS-DOS 6.21 Upgrade Setup.
