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

- Microsoft COM Transaction Integrator for CICS and IMS, versions 1.0, 4.0 SP2 
- Microsoft SNA Server, version 4.0 SP2 
-------------------------------------------------------------------------------

SUMMARY
=======

After successfully implementing a Microsoft COM Transaction Integrator for CICS
and IMS (COMTI) application using SNA Server 4.0 Service Pack 1 (SP1), this
release of SNA Server is uninstalled and SNA Server 4.0 Service Pack 2 (SP2) is
installed.

Afterwards, COMTI methods fail with the following entry appearing in the
application Event Log:

  Event ID: 4128
  Source: Transaction Server
  Type: Error
  Category: Class Factory Wrapper

  The run-time environment was unable to load an application component due to
  either an error obtaining its properties from the catalog, loading the DLL or
  getting the procedure address of DllGetClassObject. This error caused the
  process to terminate.
  C:\SNA\COMTI\Tagen.dll (Package: OneMoreTime) (Microsoft Transaction Server
  Internals Information: File: d:\viper\src\runtime\cfw\ccomdll.cpp, Line: 151)

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

The problem is related to the fact that SNA Server 4.0 SP2 is installed in a
different directory, by default, than SNA Server 4.0 SP1, C:\Program Files\SNA,
and C:\SNA, respectively. Those who use the defaults and have chosen to
reinstall SNA Server instead of to upgrade SNA Server may incur this problem.

There are at least two workarounds:

- Install SNA Server 4.0 SP2 using the same directory structure that SNA Server
  4.0 SP1 was installed in.

- Uninstall the COMTI application component libraries from their MTS packages,
  and then reinstall them.
