CoCreateInstance returns 0x80004002 - CodeGuru
forums.codeguru.com › showthreadFeb 20, 2002 · CoCreateInstance returns 0x80004002. Hi, I am using a com dll as inproc server. When I try to create an object using CoCreateInstance (), I got an error: 0x80004002, no interface supported. My understanding of the error code is that usually when you query an interface is not there. But I haven't done that yet.
