DoubleSpace Identifies Windows 3.1 in Standard Mode as Shell (96167)

The information in this article applies to:
    Microsoft MS-DOS operating system 6.0

    Microsoft MS-DOS operating system 6.22
    Microsoft Windows 3.1

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 attempt to run DoubleSpace or any of the DoubleSpace command line functions from the MS-DOS Prompt with Windows 3.1 in standard mode, you receive the following error message:

You are running the MS-DOS Shell. To run DoubleSpace, you must first quit the MS-DOS Shell.


This error occurs because the code used to detect MS-DOS Shell is the same as the code to detect Windows in standard mode, and the detection for Shell precedes the detection for Windows.
