IgnoreInstalledEMM=yes Not Working Properly with Windows 3.0 (66084)


The information in this article applies to:

  • Microsoft Windows 3.0
This article was previously published under Q66084

SYMPTOMS

If an expanded memory manager that was not designed specifically to work with Windows in 386 enhanced mode is loaded in the CONFIG.SYS file, the message
ERROR: Cannot install the 386 enhanced mode Expanded Memory driver
is displayed immediately after the opening logo screen appears. It does not matter what the IgnoreInstalledEMM= line is set to.

CAUSE

The line IgnoreInstalledEMM=yes in the [386Enh] section of the SYSTEM.INI file is designed to make Microsoft Windows version 3.0 ignore any unknown external expanded memory manager. This does not work properly in Windows 3.0.

STATUS

Microsoft has confirmed this to be a problem in Windows versions 3.0 and 3.0a. This problem does not occur in later versions of Windows.

WORKAROUND

Boot the machine with a CONFIG.SYS file that does not load an expanded memory manager when you need to use Windows 3.0 in 386 enhanced mode.
