Server Register Problem

In my DCOM server, during server's registration, I call
function: UpdateRegistryFromResource(IDR_ORVserver, TRUE).
There is no problem on my machine with Windows NT Workstation, but when I try register server on other machine
with Windows 95, function UpdateRegistryFromResource failed.
Return value is 2147746132. I try it also on other machines
with Windows 95 and result is: 1 success and 2 failed.
Where is the problem?

source code:
inline HRESULT CServiceModule::RegisterServer(BOOL bRegTypeLib, BOOL bService)
{
      HRESULT hr = CoInitialize(NULL);
      if (FAILED(hr))
            return hr;

      // Remove any previous service since it may point to
      // the incorrect file
      Uninstall();

      // Add service entries
      hr = UpdateRegistryFromResource(IDR_ORVserver, TRUE);
      if (FAILED(hr))
            return hr;

      // Adjust the AppID for Local Server or Service
      CRegKey keyAppID;
      LONG lRes = keyAppID.Open(HKEY_CLASSES_ROOT, _T("AppID"));
      if (lRes != ERROR_SUCCESS)
            return lRes;

      CRegKey key;
      lRes = key.Open(keyAppID, _T("{A8E3E5D4-F6BA-11D1-8F39-006097CA2FEA}"));
      if (lRes != ERROR_SUCCESS)
            return lRes;
      key.DeleteValue(_T("LocalService"));
      
      if (bService)
      {
            key.SetValue(_T("ORVserver"), _T("LocalService"));
            key.SetValue(_T("-Service"), _T("ServiceParameters"));
            // Create service
            Install();
      }

      // Add object entries
      hr = CComModule::RegisterServer(bRegTypeLib);

      CoUninitialize();

      return hr;
}

This will sound silly, but UpdateRegistryFromResourceID() uses the ATL registrar which is a COM interface implemented in ATL.DLL.  The error you're getting indicates that that interface is probably not registered.  So, you'll want to check if ATL.DLL is installed and registered on the 95 machines that it failed on.  You should also check to make sure those 95 machines have DCOM95 installed as well.

You can do that, or statically link to the registrar code. Define DECLARE_REGISTRY_RESOURCEID in your object's declaration, and at the top of stdafx.h, add #define _ATL_STATIC_REGISTRY (this is from the VC/ATL docs).
