League of Legends.exe Deletes Itself

After the anti-cheat update, they dished out an updated client in the 'known issues' thread. Problem is that when I unzip the files, the .exe deletes itself after about 10 seconds. At one point I managed to force it to not do so, but it deleted itself from the /deploy folder eventually, and now I can't get it to stick again. {{sticker:slayer-jinx-unamused}}
