I cannot seem to run League of Legends since I updated my PC after the whole NSA/Ransomware debacle earlier this year. My PC was not turned on since sometime last year, so I wan't affected by the virus at all. However, ever since I did update Windows, I cannot seem to launch the League Client. When I press the 'Launch' button from the Launcher, everything 'League' stops then and there(evidenced by the open Task Manager process list). When I try to launch the 'LeagueClient' straight from the program list, I just get the 'This app can't run on your PC. To find a version for your PC, check with the software publisher.' message. A lot of people seem to have an XBOX-app-related solution, but I do not see that coming into play anywhere for my situation. When I go to the 'Compatibility tab' in the 'Properties' for League of Legends, there is not a selectable compatibility mode for Windows 10; the most recent is Windows 8. I've tried re-installing to no avail, and popular user-suggested 'fixes,' such as running as Administrator and deleting the 'lol_patcher' and 'lol_launcher' folders prior to opening the shortcut, but nothing has worked. If there is an obvious thing that I am missing, I would love to eat my shoes and be told the simple solution. I want to play your game, Riot; please help me do so.

Every time I try to open League of Legends on my Mac, it says that it cannot run from the .DMG and it opens up my files to select an area to save it but everything is greyed out and I can't select anything. I have tried to re-install it multiple times. This first occurred when I opened my mac from sleep and it said that my League of Legends couldn't open. I then un-installed it and re-installed it to see if this would resolve the problem. It allowed me to open it and update it. I then slept my mac and awoke the next day to see that League of Legends closed down and wouldn't run. I then again tried to un-install and re-install however it didn't work. Please help!!!!
