This article was previously published under Q201191 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 use 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. You do not
have to register ATL70.dll, however, you must register ATL.dll 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. For additional
information, click the article number below to view the article in the
Microsoft Knowledge Base: 244955 PRB: MinDependency Project May Need to Include Atl.dll
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: OS\SYSTEM (UNICODE version)
OS\SYSTEM\ANSI (ANSI version) Location of ATL.DLL in the Visual C++ 6.0 CD: DevStudio\VC\Redist (UNICODE version)
DevStudio\VC\Redist\Ansi (ANSI version) Location of ATL70.DLL in the Visual C++ .NET CD: Win\System (UNICODE version)
Win\System\ansi (ANSI version)
