The following are the top three reasons an ATL server might

fail to register: 1. You built your project with

_WIN32_WINNT=0x400 (the default), and you are not running

the ATL server under Windows NT 4.0 or you do not have an

up-to-date version of Oleaut32.dll. To solve this problem,

run "DUMPBIN /EXPORTS OLEAUT32.DLL" and search for

UnregisterTypelib. If it is not there, then your server

cannot run. Remove this #define statement from Stdafx.h if

you want to run the ATL server under Windows 95 or older

versions of Windows NT. Alternatively, you can use

LoadLibrary and GetProcAddress so that you can run

optimally under both Windows 95 and Windows NT 4.0. The

Oleaut32.dll that ships with the Internet Explorer 3.x is

up-to-date.

2. You built your project as MinSize and Atl.dll is not

properly installed on the system. The correct version of

Atl.dll must be copied and registered by Regsvr32. There

are Windows NT and Windows 95 versions of Atl.dll. The

Windows 95 version runs under Windows NT. However, since it

does not use the UNICODE APIs, it is slightly less

efficient. Unless you build your project as MinDependency,

you will need to install the correct version of Atl.dll and

run Regsvr32 on it before you install your server.

3. You built your project as UNICODE, and you cannot run it

under Windows 95.

The following are the steps to troubleshoot: 1. For a DLL

server, run Regsvr32 in the debugger. Open the Project

Settings dialog box and click the Debug tab. In the

Executable for debug session text box, enter the full path

to Regsvr32.exe, such as C:SharedideBinRegsvr32.exe. In

the Program arguments text box, specify the full path to

your DLL, such as C:MyprojectsMyFolderDebugMyFile.dll.

Set a breakpoint at DllRegisterServer and start stepping.

2. For an EXE server, run it in the debugger and

specify /REGSVR as its command-line argument.
