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.
