The information in this article applies to:

- Microsoft COM Transaction Integrator for CICS and IMS, versions 1.0, 1.0 SP1

IMPORTANT: This article contains information about editing the registry.
Before you edit the registry, make sure you understand how to restore it if
a problem occurs. For information on how to do this, view the "Restoring
the Registry" online Help topic in Regedit.exe or the "Restoring a Registry
Key" online Help topic in Regedt32.exe.

SYMPTOMS
========

When a COMTI application method is invoked, COMTI displays a message box with
the title "mtx.exe - DLL Initialization Failed" and the text:

  Initialization of the dynamic link library C:\program
  files\sna\COMTI\tagen.dll failed.
  The process is terminating abnormally.

When you click OK, another message box is displayed with the title "Object
Creation Failed" and the text:

  ActiveX component can't create object.

The Windows NT event log contains the following entry:

  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:\program files\sna\COMTI\tagen.dll
  (Package: CedarBank)
  (Microsoft Transaction Server Internals Information: File:
  d:\viper\src\runtime\cfw\ccomdll.cpp, Line: 151)

CAUSE
=====

At run time, Tagen.dll must have access to the Windows NT registry key that
identifies the location of a message DLL needed for writing an informative
message to the Windows NT event log. However, Tagen.dll attempts to get Write
access to the registry key, when only Read access is required. The default user
profile does not have that right, only Administrators do.

WORKAROUND
==========

Method 1
--------

Start User Manager for domains and assign the Windows NT User (...of the identity
under which the Microsoft Transaction Server package component is to execute) to
the Windows NT Administrators Group.

Method 2
--------

WARNING: Using Registry Editor incorrectly can cause serious problems that may
require you to reinstall your operating system. Microsoft cannot guarantee that
problems resulting from the incorrect use of Registry Editor can be solved. Use
Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys And
Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete
Information in the Registry" and "Edit Registry Data" Help topics in
Regedt32.exe. Note that you should back up the registry before you edit it. If
you are running Windows NT, you should also update your Emergency Repair Disk
(ERD).

1. Start Registry Editor (Regedt32.exe).

2. Locate the following key and select it:

  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EventLog
  \Application\COMTI

  NOTE: The above registry key is one path; it has been wrapped for readability.

3. Click Permissions on the Security menu.

4. Confirm that the Windows NT Group, Everyone, has either Read or Special
  Access permission for this registry key.

5. Select the Name, Everyone. Click Full Control on the Type of Access menu.

6. Click OK.
