SUMMARY
=======

To enable the latest DCOM components for Windows 95 and Windows 98 computers,
Microsoft has made DCOM98.exe and DCOM95.exe available.

The Visual Basic and Visual Studio installation programs install DCOM98.exe.
DCOM95.exe version 1.3 is available for download from the Microsoft Web site.
This article describes the key differences between these two versions.

MORE INFORMATION
================

Distributed COM (DCOM) enables applications to communicate between two machines.
DCOM is native to the Windows 2000, Windows NT (beginning with version 4.0) and
Windows 98 operating systems. DCOM must be installed on Windows 95 computers to
enable this functionality.

DCOM98.exe and DCOM95.exe are installation utilities that install or update DCOM
components.

The following sections provide specifics about each version.

DCOM98
------

- DCOM98 installs the DCOM components on both Windows 95 and Windows 98
  computers. The components that DCOM installs on Windows 98 computers are
  newer than those that ship with Windows 98 and are required by some
  components of Visual Basic to run properly.

- DCOM98 ships with Microsoft Visual Basic 6.0.

- DCOM98 can be installed automatically by the Visual Basic installation
  program.

- DCOM98 is available on the Visual Basic installation CD-ROM in the DCOM98
  folder.

DCOM95
------

- DCOM95 version 1.3 installs the latest DCOM components ONLY on Windows 95
  computers. DCOM95 is not intended to and will not install on Windows 98
  computers. If you have installed DCOM95 version 1.3, you do not need to
  install DCOM98 on the client computer.


- DCOM95 is newer than DCOM98. If you would like your Windows 95 clients to run
  the latest DCOM components be sure they install DCOM95 version 1.3.

- DCOM95 version 1.3 is available for download from the following Web site:

  http://www.microsoft.com/com/dcom/dcom95/dcom1_3.asp

Some applications that were created with Visual Basic need to have DCOM installed
to ensure that some components run properly. Use DCOM98 or DCOM95 to install
these necessary components.

For more details about the specific differences between DCOM95 and DCOM98, please
refer to the Release notes (RelNotes.Txt) for each version. The Release notes
are installed to the following directory after installation:

  \\Windows\System\DCOMxx

where "xx" is 95 or 98. The Release notes for DCOM95 are also available on the
following Web site:

  http://www.microsoft.com/com/dcom/dcom95/relnotes.asp
