Hi! I updated the program to version 4.1.0 and found that my VB.NET application stopped working. Your example (COM_TestForm) does not work either. I rolled back to version 4.0.4 and it worked.
Same problem here. I have also rolled back to 4.0.4
Same problem for me. I had to roll back to 4.0.4 version and that brought the coding back to work.
Error message in Office mentioned "Automation error", code x'80131500
Likewise in C#. Not even when I rebuild the app with the new COMwrapper.
Same, I am also having issue with version 4.1.0. VBA and all the API examples are not working.
