Hi Vikas,
Set the following Environment Variable –
Go to START > ‘Edit the System Environment Variables’ > click Environment Variables.
Under the System Variables, please click NEW and create a new variable.
Variable Name – FLEXLM_TIMEOUT
Variable Value – 50000000
Save it.
Now open a file explorer and type %appdata% in the address bar.
Locate the Ansys folder and rename it to Ansys.old.
Now try launching the application and run the simulation to see if it runs without any issue.
