On my development machine in registry there is following record HKEY_CLASSES_ROOT\ObjectDBX.AxDbDocument.18\CLSID, but on the machine that's throwing the error, there isn't.
Please check the attached picture from my dev machine.
I can create this registry folder hierarchy through Registry Editor, but how to create the last record with name: (Default) and Data: {EBF0F8FD-632A-4AB8-8D71-E77217898747}.
I copied just this simple method for registering dll into registry. When I am calling ASDDSA inside AutoCad on my dev machine the number 33 is returned.
The lisp function has to make the same thing that I am trying to accomplish manually with Registry Editor, isn't it?
(defun C:ASDDSA()
(startapp "regsvr32.exe" (strcat "/s \" C:\axdb.dll\""))
)
