Hi, 


Please check whether you have any previous ANSYS products running on your PC other than student products? If yes then please uninstall all along with previous ANSYS license manager. 


Then install ANSYS student products, no license key is needed for R18.0 and above. Which version are you using?


Also make sure that your computer is showing correct date and time.


I hope this helps.
