Exactly the same thing for me and my son, both on windows 10 pc's.
This is rubbish, some w10 pc's work some don't, between Microsoft and riot, this is a joke.
we have tried tickets and get the standard response....it's your router, it's your firewall, it's your coffee!!!!
BS riot, the patcher worked fine before w10, now it doesn't, fix it, or post HELPFUL information that can actually repair and get this game to work again on w10.
I don't mind so much being a BETA tester for windows (Jokes), but to be ignored and dismissed by you riot, is appalling.
I have spoken to a few people at work about this and they are having the same issues, and again, echo my position and sentiments, on riot not being actively on these message boards, assisting players....not with the stupid links to the same crap that doesn't fix anything, but to actually investigate WHAT the hell is stopping some w10 pc's from running league at all.
It has been over a month now, and we have not been able to play, elo going south no doubt, but at least we are not wasting our hard earned cash on your game!!
For the record, we have sent tickets, and tried EVERY fix suggested on your website pages, and internet in general
For the record again, 2 of the PC's that have NOT been updated to w10 on our network work fine!
Thanks for the non existent solid help guys....appreciate it!
