Ehh, the engine could work with VB .NET in theory but that is defiantly not supported and will most likely result in some very strange behaviours. The engine is coded in Visual Basic 5 and its target language platform is Visual Basic 5 and Visual Basic 6. I probably can't help you with VB .NET issues with the engine, but I've got VB .NET (the 2002 version) installed, so I'll take a look at it tomorrow. It's 10 minutes past 2 AM in Denmark, and I should probably go to bed.

Sorry, I'll try to read the question before answering next time. I didn't read that you were trying to run the first tutorial - the error I talked about also throws an "Automation error...".
But I think I know what wrong. Wait a min, better read you question again... No, actually I don't. I thought it was something, but the tested it at it wasn't that.
If you still havn't figured out what is wrong (and if you havn't changed anything) then try removing the reference to the engine DLL and add all the classes from the engine source instead. This way, when you encounter the error hit "Debug" and you'll get a more specific debugging answer than error in "Engine.Render".

Prehabs. If the error occurs when closing a program, the reason is that the Engine-class is unloaded but the program still tries to execute a function from that class because the loop isn't ended. The trick is to make sure the loop is ended before closing the application. The following code ends the loop to get a clean unload procedure.
  
Private Sub Form_Unload(Cancel As Integer)  
  'If loop isn't ended  
  If Running = True Then
    Cancel = 1 'Cancel the termination of the app  
    Running = False 'End the loop at first given chance  
  End If
End Sub
