PRB: SYS2070 Issued When Running PWB.EXE for the First Time (61572)


The information in this article applies to:

  • Microsoft Programmer's Workbench for OS/2 1.0
  • Microsoft Programmer's Workbench for OS/2 1.1
This article was previously published under Q61572

SYMPTOMS

When running the Programmer's WorkBench (PWB) for the first time, the following OS/2 system error may be issued:
Session Title:
PWBED.EXE

SYS2070: The system could not demand load the application's segment. MSHELP HELPSHRINK is in error. For additional detailed information also see message SYS0127

CAUSE

This problem is usually caused as a result of the Setup program not being able to copy its version of MSHELP.DLL over the old version of MSHELP.DLL. If another process (most likely a detached session of QH.EXE) was accessing this file during the execution of Setup, the Setup program will issue a message similar to the following:
ERROR: Could not create file C:\OS2\DLL\mshelp.dll ERROR: File copy failed: A:\the PWB\mshelp.dll to C:\OS2\dll\mshelp.dll

RESOLUTION

To solve this problem, take the following steps:

  1. Disable QH as a keyboard monitor:

    1. Press ALT+Q (to invoke QH).
    2. Press O (for the Options menu).
    3. Press T (to terminate the monitor).
  2. Copy the up-to-date version of MSHELP.DLL from the distribution disk:

    1. Insert the Setup/Compiler 1 disk into drive A.
    2. Change the default drive A.
    3. Run Setup with the /copy option by typing the following:

      setup /copy

    4. Press ENTER
    5. Press ENTER again (unless the setup files are in a drive other than A).
    6. At the prompt asking for the name of the file to copy, type MSHELP.DLL and press ENTER.
    7. At the prompt asking for the name of the directory to which to copy this file, type the directory in which the old MSHELP.DLL is located (most likely C:\OS2\DLL).
    8. Setup should then ask for the Programmer's WorkBench/Utilities for OS/2 disk to be inserted into the setup drive.
    9. When Setup is finished copying the file, press ENTER at the next prompt.
The PWB should now start up correctly.

NOTE: SQL Server's Setup program also installs its own version of MSHELP.DLL onto the system. The SQL Server Setup places its copy of this DLL into a directory called \SQL\DLL. If this directory is in the LIBPATH before the directory into which the latest MSHELP.DLL was placed, this same problem can arise.
