Hi Werner,
Think I have found a possible cause of the problem you observe.
To check this I have produced a simple test application which I would ask you to run and check the results – there is an executable and text file with instructions in the attached zip.
As it says in the instructions – please ensure that you do not have any other instances of Excel running when you run the test application – and then if you could send the results back as per the notes that would be great.
You will see that if you can create an instance of Excel by pressing the button create then I have a solution for you 🙂
Any questions please ask.
BR
Adrian
