The problem didn't exist before, but now when trying to launch Abaqus CAE, I get "Abaqus CAE exited with an error". I followed the instruction on setting hardware acceleration per QA article QA00000009378, but that didn't work either. I tried installing a newer version of Abaqus CAE 2018, but that too couldn't launch just like Abaqus 6.14. Abaqus 6.14 used to work on this very same computer. What can I do to launch CAE? Thanks.
