Hello

I've not been able to open the Fluent application from the Workbench. I only got the message "The FLUENT application failed to initialize."

When opening it standalone, the console shows ">Unexpected license problem; exiting. >Hit return to exit."

I'm using the free student version (2024 R1) and the other applications I use are working as intended.

How can I solve this?

Hi Germannu,

Do you have any other versions installed too beside v241?

Try to rename a few configuration folders. 

1. Go to the start menu and search for %appdata% and rename it to ‘ansys.old’ and type %temp% rename .ansys to .ansys.old 
2. Go to the ‘C:\Users\user_name’ path and rename .cfx’ folder to ‘.cfx.old’
3. Go to the ‘C:\Users\user_name’ path and rename ‘fluent.conf’ to ‘fluent.conf.old’

I did have v222 version and it seems some files remain.

I followed suggestions 1 and 3 (I don't have the .cfx folder) and now the fluent starts from the workbench, but behaves like it did opening standalone early. Workbench doesn't recognize the fluent is open and still unable to link the project.
