I have paid for 3Dexperience Catia (students). But initially when I downloaded, it was not opening. So I deleted all its files including 3Dexperience launcher. Then I re-downloaded the launcher and tried to download the program, but the launcher was not showing anything for downloading the program. Can this issue of 3Dexperience launcher be fixed, so that I can again download 3Dexperience Catia (students)?
