Windows Err Msg: Not Enough Environment Space

ID: Q105668

The following information applies to:

Microsoft Windows operating system versions 3.0, 3.0a, 3.1, 3.11

Microsoft Windows for Workgroups versions 3.1, 3.11

SYMPTOMS

You may receive the following error message when you start the MS-DOS Prompt or an MS-DOS-based application:

Not Enough Environment Space

CAUSE

The above error message may occur if you are running Novell NetWare and have not installed Windows with Novell connectivity, or if the MS-DOS-based application you are trying to run requires more than 256 bytes of environment space.

WORKAROUND

If Windows 3.0 or later is running on a Novell NetWare network, make sure that the appropriate network selection is made in Windows Setup.

If the MS-DOS-based application requires more than 256 bytes of environment space and you are running Windows 3.1 or later, add the following line to the SYSTEM.INI file under the [NonWindowsApp] section:
```
   [NonWindowsApp]
   CommandEnvSize=1024 
```
1024 bytes should work properly; however, the setting can be set as high as 32,768 bytes. The value must be either zero or between 160 and 32768.

This is a global setting that affects all virtual machines (VMs).

With Windows 2.x and later, you can create a program information file (PIF) to increase the environment space for the single application. Use the following settings in the PIF:

For Windows 3.0:


   Field                          Setting
   =====                          =======

   Program FileName               Command.COM
   Window Title                   My Program
   Optional Parameters            /e:2048 /c C:\mydir\myprog.exe
   Startup Directory              C:\mydir

For Windows 2.x:


   Field                          Setting
   =====                          =======

   Program Name                   Command.COM
   Program Title                  My Program
   Program Parameters             /e:2048 /c C:\mydir\myprog.exe
   Initial Directory              C:\mydir

"/e:2048" is the size of the environment space in bytes; this value also ranges from 160 to 32768.

"Mydir" is the name of the directory that contains the executable of the program.

"Myprog.exe" is the name of the program.

"/C" specifies that the command processor is to execute MYPROG.EXE and then terminate itself.
