vanaja · Answer

Yes i am using third party dll which will generate htms and js. This error appears when creating an object for the class. And also i checked the registry in regedit the registry is not present within CLSID instead it is present in the dll name. My com dll version is 32bit and i am trying to register it in windows7 64 bit.
