Can´t install LoL

Hey, when downloading the patches during the first installation of the game at some point the installer always aborts the process. I tried it with avira closed and as admin and still got the same results. Bug Report says this: Additional File ---------------------------------------------------Path LoLPatcherN6KH4Q16.dmp* -------------------------C:\Users\Username\Appdata\Local\Temp F9CL4N24.xml* --------------------------------------------------C:\Users\Username\Appdata\Local\Temp 2016-05-09T21-12-39_LoL...-------------------------D:\Programme (x86)\Riot\Logs\Patcher... 2016-05-09_21-26-14_LoL...-------------------------D:\Programme (x86)\Riot\RADS\project... Can you give me advice to solve the problem? Sry for my bad english.
