-------------------------------------------------------------------------------
The information in this article applies to:

 - Microsoft PowerPoint for Windows 95, version 7.0 
 - Microsoft PowerPoint for Windows, versions 4.0, 4.0a, 4.0c 
 - Microsoft Video for Windows, versions 1.0, 1.1 
-------------------------------------------------------------------------------


SUMMARY
=======

To provide the ability to incorporate various multimedia data types into
PowerPoint, the run-time files for Microsoft Video version 1.1 for Windows
(including an OLE [object-linking-and-embedding] version of Media Player) are
included with PowerPoint 4.0.

Several video compressor/decompressor (codec) files are provided with these
run-time files, but not all of them work with Microsoft Windows NT because Video
1.1 for Windows is written for Microsoft Windows 3.1.

As a result, .AVI files that are inserted into a PowerPoint 4.0 presentation may
play correctly with Windows 3.1, but may not play with Windows NT or Windows
95.

If you try to play or edit an .AVI file that doesn't use one of the supported
codec files, the following error message appears:

   There is no driver installed on your system.

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

To determine which codec file has been used to compress an .AVI file, do the
following under Windows 3.1:

1. Open the .AVI file in Media Player. If you performed a complete setup of
   PowerPoint under Windows 3.1, the Media Player is in the same Program Manager
   group window as the Microsoft PowerPoint icon.

   -or-

   If the .AVI file has already been inserted into a presentation using Media
   Player, select the object in your presentation and choose Edit from the list
   that appears when you choose Media Clip Object from the Edit menu.

2. From the Device menu in Media Player, choose Configure.

3. In the Configure dialog box that appears, there is a list that contains
   information about the .AVI file that you have open.

   An abbreviation for the codec file being used is contained in the first part
   of the Video entry in this information list. For example, in the following
   entry

   Video: RLE 160x120x8 (RLE) 15.000 fps

   the letters RLE indicate that the .AVI file was compressed using Microsoft RLE
   compression.

   NOTE: This procedure does not work under Windows NT because the Video for
   Windows drivers provided with Windows NT are different than the drivers
   provided with Video for Windows version 1.1. As a result, the same
   information is not provided in the Configure dialog box when an .AVI file is
   open.

To insure that your .AVI files will play back under Windows NT, Windows 3.11, and
Windows 95, make sure that .AVI files were compressed using one of the following
methods:

   Abbreviation   Compression Name
   ------------   ----------------------------

Windows 95 is:
