The information in this article applies to:
- The Microsoft Active Template Library (ATL), versions 2.1, 3.0, used 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

SYMPTOMS
========
Registration or unregistration of ATL servers may fail on a machine if the
logged-on user doesn't have appropriate registry access rights. In-process
servers may fail and display the following message:
DllRegisterServer in projectname.dll failed. Return code was:
0x80020009.
Debug EXE servers, linked statically to the registrar code and run in the
debugger, may display the following trace messages:
Failed to register, cleaning up!
The thread 0xnn has exited with code -2147352567 (0x80020009).
CAUSE
=====
CRegKey is a class used by ATL for manipulating the registry. It's Open() and
Create() methods have a REGSAM argument that specifies the security access to
the particular registry key.
The REGSAM argument defaults to KEY_ALL_ACCESS. In several places in the ATL
code, Open() and Create() are called without specifying the REGSAM, which means
it defaults to KEY_ALL_ACCESS. KEY_ALL_ACCESS is a combination of other flags
including WRITE_DAC and WRITE_OWNER.
For a non-administrator, you may not have WRITE_DAC and WRITE_OWNER permissions,
which causes registration to fail.
RESOLUTION
==========
In ATLBASE.H, change the default REGSAM for CRegKey::Create() and
CRegKey::Open() to KEY_READ|KEY_WRITE:
class CRegKey
{
...
LONG Create(HKEY hKeyParent, LPCTSTR lpszKeyName, LPTSTR lpszClass =
REG_NONE, DWORD dwOptions = REG_OPTION_NON_VOLATILE,
REGSAM samDesired = KEY_READ | KEY_WRITE, // changed REGSAM
LPSECURITY_ATTRIBUTES lpSecAttr = NULL,
LPDWORD lpdwDisposition = NULL);
LONG Open(HKEY hKeyParent, LPCTSTR lpszKeyName,
REGSAM samDesired = KEY_READ | KEY_WRITE); // changed REGSAM
...
};
You need to link statically to the registrar. Building for ReleaseMinDependency
will statically link to the registrar. Debug builds link dynamically to the
registrar via Atl.dll. You need to add _ATL_STATIC_REGISTRY to the list of
Preprocessor definitions. You can do this on the Project menu by clicking
Settings. Click the C/C++ tab and select General under Category.
