>Take a look a MS Knowledge Base Q146219...this is what I am struggling with. My routine ensures that the five required dll files are installed on the client machine but I still receive the error when registering the file.

The 5 files being:

mfc30.dll  olepro32.dll  msvcrt20.dll  mfc40.dll  msvcrt40.dll

Are you getting "Error: OLE Error Code 0x80040112: Appropriate license for this class not found." Is this for a particular OS or across the board?
