well ive downloaded the patch , clicked on the play botun but it couldnt load the login screen ...with theses moves is it posible to get fixed ?

followed the steps and patcher loads, but after clicking the play button nothing loads up.... guess im retired from LOL now?

Anybody still looking for a fix I recently upgraded to windows 8 and it gave me this problem, After trying everything and nothing working I changed compatibility to windows 7 and nothing. Tried again set it to windows xp and everything worked!

yeah im getting huge issues. the login screen does not load after clicking play on the patcher window. i have yet to try absolutely everything said in the opening message but i will attempt and see what happens. does anyone know if this problem is at all related to me having a mac that runs windows?

I was having this issue;
I uninstalled like 7 times (no exaggeration), tried just about everything that was posted on the forums, then I came across one post that the guy suggested installing both .net framework 4.0 and .net framework 3.5.
I just got home from being gone all day; my computer left to download 3.5
I just tried running the LoL patcher, and this is the first time that I didn't get the rads error.
It is patching right now as we speak.
--I'll keep everyone posted on how it turns out.

Love you thanks! <3

Hello, thought I would post my process for (finally!) fixing this. If you want to copy my process, make sure you have the exact same OS:
I am running XP pro (32bit) SP3 on a custom box.

Originally, I downloaded normally to F: drive (which is my boot drive btw), got the error immediately upon opening. Tried un/reinstall to no effect. Then tried installing C++ which I don't think I had before (point of interest, if you need this, make sure you download the 2010 or latest version for your OS and get the x86 version if your OS is 32 bit, this can be confusing as there is a separate 64bit version) and dot net framework v4. No dice.

Finally, I decided to uninstall everything, including dot net and C++ (which it turns out I had multiple versions of in my program list), neither of which had I uninstalled previously. I reinstalled starting with dot net--this time v3.5 as v4 is in beta currently (though I've read that LOL is supposed to work with either). Next I reinstalled the 2010 C++ x86 redistributable package. Finally, (and as it turns out, using the same setup files I originally downloaded) reinstalled LOL. Also at this time I tried that DNS trick (using 8.8.8.8 and 8.8.4.4 as my default and additional DNS servers) with a quick DNS flush and restart. When I logged back into windows, LOL started up like a charm. No further issues.

hey im still having this problem failed to launch RADS\system\rads_user_kernel.exe i seriously have tried everything i need SOME HELP PLZZ !?
