I just downloaded ansys 19.1 student version. When i'm launching Fluent application it says "Fluent application failed to start". What to do?

One of the most common causes of this issue is graphics.
Please try running Fluent in non-graphic mode by using this command in the CMD Prompt (change your installation directory accordingly)
"C:Program FilesANSYS IncANSYS Studentv191fluentntbinwin64fluent.exe" ^-r19.1.0 3d -g -meshing
Does this work ? If so, you have issue with graphics. If not, this is something else, please attach the screenshot of the error that you see here.

That command was to try running Fluent in non-graphic mode to identify if graphics is the issue. It's not intended to fix the issue that you currently have.
From the screenshots that you sent, it seems both modes have the same issue that it got stuck when it's trying to spawn processes.
Let's try to rule out another issue.
In Fluent launcher (either launch from shortcut or run this command "C:Program FilesANSYS IncANSYS Studentv191fluentntbinwin64fluent.exe" , with quote)
try this setting
Processing Options : Parallel (Local Machine)
Processes : 0
GPGPUs per Machine : None
Can you launch successfully with this setting ? If so, something on your systems prevent you from spawning multiple processes. Check your security/anti-virus software.

rename folder v191 in this directory
%AppData%Ansys (please copy and paste this in the Windows Explorer address bar)
to anything else (e.g., v191.old)
and try with test project again.

Fluent looks to have started, but isn't reading the mesh. Just to confirm you have a 3d mesh and not a shell? Can you open any of the tutorials available via the Help system?

I am facing similar issue on Ansys version 19.2 (Fluent).Geometry,meshing works fine only setup file doesn't start but pops up with an error window saying "The FLUENT application failed to start".

If you create a new Fluent workflow can you open Fluent then?

Drag a Fluent component onto the Workbench system and do NOT connect to anything else. Will that open? Just want to double check it's not your mesh: what are the messages?

Still it doesn't open. pops up same thing. Opened new workbench 2019 R2--->drag and drop fluid flow (fluent)-->double click on setup-->Ok on launcher ( no changes done- 2d,serial,double precision).
