Our teams are looking into the issues that several people are experiencing with the new patcher.

Some things that have been working for people:
- Run as administrator
- Give the patcher some time to run
- Do not click during League of Legends logo
- Be sure to install to C:\Riot Games

We will continue keep the community updated. If you have not checked out the sticky from, Eambo please see the following http://www.leagueoflegends.com/board/showthread.php?t=714338

Please post your issues here so our engineers can review what problems you are experiencing.

----- Edit -----
Please know that everything will be fixed when the patcher is hot fixed/updated. Please try the following as a temporary work around:

Update:Please provide the logs in your RADS folder so we can view the different errors that people are receiving. This will greatly help us to resolve the issue throughout different environments. These logs will be forwarded directly to our RADS team for further review.

Update: I would like to thank everyone again for providing their logs and information about the patcher. This is the most recent update I have received from our RADS team.

1. Download http://l3cdn.riotgames.com/releases/...ser_kernel.exe (http://l3cdn.riotgames.com/releases/live/system/rads_user_kernel.exe)
2. Replace <install directory>/RADS/system/rads_user_kernel.exe with this file.
3. Try launching it again

now it works and launches but now i cant connect to the pvp.net server any help on this one?

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.

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 and 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.

Leib Olmai:
One thing that might help is to get CCleaner and run Registery clean after patch.
After the migration, I've found 3149 registery errors with it. With the last hotfix I've found 2. Every patch there's error related to LoL. For the people who had Custom skin, it might also help to run those.

I've been doing that since I play LoL, running CCleaner after each patch (patch finish, close client, run CCleaner) then reopen the patch. I never, ever had one patcher problem.

Alot of DLL error can be find, and I guess it's because riot change their path of folder or whatever they change often.

But I'm pretty sure CCleaner help, alot.
