Interop Error

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.

 Are you using any third party control or MS Office Interops or related to SQL Server etc..

 You must provide more information about the problem..
