  Hello,
  
  I was hoping someone could help me out and try to fix my issue.
  
  Issue:
  
  Fluent will not start in the workbench nor outside of the workbench (I also tried running as administrator). In both cases, when I try opening fluent, a window pops up and closes within a fraction of a second. I don't know what the windows says since it closes so fast.
  
  I reinstalled Ansys 2019 R1 and the problem still persists. I am not sure what I should do to fix this problem. Any help or guidance would be greatly appreciated.
  
  Thanks,
  
  David

  Hi David,
  
  Try opening CMD Prompt, and issue the following commands
  
  set PATH=C:WINDOWSsystem32;C:WINDOWS;C:WINDOWSSystem32Wbem
  
  "%AWP_ROOT193%fluentntbinwin64fluent.exe" -r19.3.0 3d -g
  
  Does this show any error or if it launches fine ?
  
  Also, what's the output of
  
  dir /s "%AWP_ROOT193%fluent*.dmp"
  
  Thanks,

  I got the following message after running first command. I got a couple of windows pop up asking for permission to allow through firewall. I let them through. That was it, fluent did not launch.

  Hi davidrivas,
  
  Are you saying that fluent is still not launching properly?
  
  It looks like it did launch according to the logs. If it is still failing what is happening exactly after it starts up?
  
  Thank you,

  Hi David,
  
  As Jake mentioned, when you used this command
  
  "%AWP_ROOT193%fluentntbinwin64fluent.exe" -r19.3.0 3d -g
  
  it did launch Fluent just fine. Sorry, I forgot to note that the command only launches Fluent in non-GUI mode. This is to test whether you have any issue with graphics, which seems to be the case here.
  
  Can you try just the above command again (to run a non-GUI mode) without running the following command
  
  set PATH=C:WINDOWSsystem32;C:WINDOWS;C:WINDOWSSystem32Wbem
  
  If this still works, the issue is with your graphics.
  
  If it doesn't work, the issue is with your Path environment variable. Make sure you have C:WINDOWSsystem32;C:WINDOWS;C:WINDOWSSystem32Wbem in front of any entries in your Path environment variable, ref:

  Thanks,

  Hi Jake,
  
  Essentially when I try opening Fluent in the workbench a window appears on my screen for approximately a millisecond. This happens too fast to read what the window says. That's is, nothing happens after that windows disappears. Workbench does not display any errors.
  
  Win,
  
  After running Fluent in non-GUI as instructed, the CMD prompt provided the same lines as before (reference below). I went ahead to check my Path value, current it is:
  
  %USERPROFILE%AppDataLocalMircosoftWindowsApps
  
  Is this okay?

  Hi David,
  
  I see. One last thing to try. Try launching Fluent GUI mode from CMD Prompt
  
  "%AWP_ROOT193%fluentntbinwin64fluent.exe" -r19.3.0 3d
  
  Does this work ? if not, you are experiencing a graphics issue.
  
  Try updating graphics driver or 'rolling back' driver to original driver and see if that makes any differences.
  
  Otherwise, you may need to find some dedicated graphics card for your machine. Here is the list of cards that have been tested
