Autodesk Inventor Nastran 2020 Keygen

I am having the exact same issues. I am running Inventor Professional 2022 and Nastran 2022. I have double checked to make sure there are no hidden dialog boxes. I tried opening and closing of inventor as suggested. I have uninstalled and reinstalled nastran. I have not uninstalled inventor.
