Answer :
The ATL 2.0 Object Wizard might not be present in the Component Gallery. The ATL 2.0 Object Wizard is not installed by the main ATL 2.0 setup program (Atlinst.exe).
It requires a separate setup program. You need to download and run the ATL 2.0 Object Wizard Technology Preview (Objinst.exe) from the ATL Web page. There is a separate ZIP file for Windows NT 3.51.
The ATL 2.0 Object Wizard may crash if an older version of Oleaut32.dll is installed on the system. Make sure the version of Oleaut32.dll is at least 2.20.4049. The latest version is available for download at the Internet Explorer 3.x Web site. If this does not fix the problem, then install Service Pack 2 for Windows NT 4.0.
