Run-time error when running API

When you're running the erwin dm API and get the error:

Run-time error '429':
ActiveX component can't create object 

The reason for such an error is usually the references to the correct Objects are missing.

Navigate to the ERwin installation folder  (For example C:\Program Files\erwin\Data Modeler r9)
Right-click the file: EAL.DLL
Choose "Open With"
Click on: "Choose Program..."
Choose: "Browse..."
Use browse to navigate to the Windows system folder (e.g. "C:\Windows\System32")
Find the file: regsvr32.exe
Invoke regsvr32.exe (double-click, or right-click and choose "Open")
You should see a message saying that the registration succeeded.
Repeat these steps with ERXML.DLL

Make sure you have full control windows privilege to the folder/files above.
