The information in this article applies to:

- Microsoft Outlook 97, version 8.03, on platform(s):
   - the operating system: Microsoft Windows NT 
- Microsoft Exchange Server, version 5.5 
-------------------------------------------------------------------------------

SYMPTOMS
========

When you install the Microsoft Outlook client on a Microsoft Exchange Server
computer, you may receive the following error:

  Setup cannot register COMCAT.dll in the system registry
  because an older version is in use. Close all applications
  and try again.

CAUSE
=====

The Microsoft Exchange Event Service that uses the Comcat.dll file may be
running. This behavior is by design.

RESOLUTION
==========

Stop the Microsoft Exchange Event service in the Control Panel Services icon
before starting or continuing with the Outlook installation.
