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

 - The Microsoft Active Template Library (ATL), versions 2.0, 2.1, 3.0, included with:
    - Microsoft Visual C++, 32-bit Enterprise Edition, versions 5.0, 6.0 
    - Microsoft Visual C++, 32-bit Professional Edition, versions 5.0, 6.0 
    - Microsoft Visual C++, 32-bit Learning Edition, version 6.0 
    - Microsoft Visual C++.NET (2002) 
-------------------------------------------------------------------------------

SYMPTOMS
========

When you register an ATL server, you might get error 0x80040154 (Class not
registered). For DLLs, REGSVR32.exe returns this error. For .exes, the call to
_Module::RegisterServer(CComModule::RegisterServer) in _tWinMain() returns this
error.

CAUSE
=====

ATL70.dll is not installed, or it is not registered.

NOTE: For Visual Studio 6.0 and earlier, the ATL runtime is contained in ATL.dll.
If you are using Visual Studio 6.0 or earlier, use ATL.dll instead of the later
Visual Studio .NET version.

RESOLUTION
==========

Install ATL70.dll (or ATL.dll for earlier versions of Visual Studio) in the
Windows\System or Winnt\System32 directory, and then register it by using
Regsvr32.exe. There are UNICODE and ANSI versions of ATL70.dll and ATL.dll.
Install the appropriate version on the target operating system (that is, UNICODE
for Microsoft Windows NT, and ANSI for Microsoft Windows 95 or Microsoft Windows
98).

NOTE: The following steps apply only to Visual Studio 6.0 and earlier. Visual
Studio .NET does not have a MinDependency build target.

As an alternative, do not use ATL.dll. When you rebuild your ATL server with a
build target of ReleaseMinDependency, the code in ATL.dll is statically linked
to your project.

Even for a 'Release MinDependency' ATL.dll may need to be shipped.

STATUS
======

This behavior is by design.

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

ATL has a registrar component that is used during registration. This component
resides in ATL.dll. During registration, the error 0x80040154 is returned from
CoCreateInstance() when it fails to create the registrar component.

Location of ATL.DLL in the Visual C++ 5.0 CD::

Location of ATL.DLL in the Visual C++ 6.0 CD::
