  Hi, I'm having trouble opening the Fluent software. It worked perfectly until yesterday, but it fails to validate its connection when I click 'Start'.
  I noticed it changed the working directory from C:Users to the one in the image below.
  I already tried reducing the number of cores but the issue persists and Fluent doesn't start itself at all - it worked perfectly with 10 cores yesterday.
  Would appreciate help regarding this problem, thanks!

  Please try changing the working directory to a writeable directory with no special characters.
