Before installing SHARE.EXE on any system, first determine the version of MS-DOS being used. Under MS-DOS 4.x, SHARE.EXE must be loaded in the CONFIG.SYS file with the correct parameters (/F:5100 and /L:500), even if it is already in the AUTOEXEC.BAT file.

To add SHARE.EXE to the CONFIG.SYS file:

  1. Open the CONFIG.SYS file in a text editor, such as Notepad.
  2. Add the following line to the top of the file:
          INSTALL=SHARE.EXE /L:500 /F:5100
  3. Save the file, exit Windows and restart the computer.


Works for Windows 3.0 loads SHARE.EXE in the AUTOEXEC.BAT file during setup. If there is a partition on the hard drive larger than 32 MB, MS-DOS version 4.x loads SHARE.EXE into memory immediately following the CONFIG.SYS files execution and before the AUTOEXEC.BAT is executed. If the file is not loaded in the CONFIG.SYS, the MS-DOS system will automatically load the file in memory, causing SHARE.EXE in the AUTOEXEC.BAT file to be ignored.
