I have tried the option "Do not allow loading/save other workbooks", but it does not give the result I was hoping for. This is what happens now.
- Start the protected application 'myapp.exe' with the setting ' Do not allow ...'; Excel opens as expected.
- Open a new unprotected Excel from the Windows desktop, e.g. 'Book1.xlsm'.
This gives the following error, which I am sure, customers don't understand why their Excel is 'not working' anymore.
Am I doing something wrong? Or better, how can I make sure the workbook opens normally?
