Raj, thank you for your reply. Please see my response below per your instructions.
Also set the environment variable ANSYSLMD_LICENSE_FILE = portno.@servername in your system environment settings and try to relaunch the application.
I assume "portno." is "port number". What does this port number can be?
In your start menu type %temp%> .ansys> over there will be a file named "*rocky", please share screenshot of that file.
The screenshot is below. I am also copying and pasting the content in the file "licdebug.INL466957.ROCKY.241" for your inspection. I do see error related messages. Hope that would give you clue how to fix the issue.
