Licence Refresh without changing the version of ansys
I have referred to the instructions below and I am trying to renew my Ansys license
I have extracted all the files and proceeded to the "student" folder. I see the "WINX64.7z" here but I cannot extract or unzip this. When I try to open i, it only opens as a note pad file
Could you please tell me how can I unzip or extract this "WINX64.7z" file?
