I have used Solidworks 2015 for the last year for school. Now I need to renew/upgrade to 2016 for a class and I can't get it to upgrade. Whenever I try to click on the "install now" button, I'm told that there are additional files required. I have included an image showing the window. I don't know what else to do and have had little to no luck searching (although I may not know what to search for). I really need to get this done so I can get some assignments done and would REALLY appreciate any help.
