So today I upgraded my pc from XP to Windows 7. I re-downloaded LoL and after it finished downloaded and installing, I logged in as per usual just to make sure everything was in working order. I logged in with no problems, could navigate through menus and check my friends list, but after I closed the application, I haven't been able to get it to work again.

All it does when I start the launcher is immediately throw up an error saying:

"Update Failed
Unspecified error occured. Please check the logs for more information."

It gives me the option to Continue, which lets me stare at a useless launcher, or Send Logs, which so far has only caused the process to Not Respond and crash/I have to force-kill it with Task Manager.

Since it worked earlier after I just downloaded it, I can't imagine why it's having a problem now. I would like assistance in resolving this issue.

Thanks in advance.

Nevermind, it seems that I was using the wrong launcher(?). In my C:\Riot Games\Leage of Legends folder there are a lol.launcher and a lol.launcher.admin... apparently I *have* to use the admin version in order to launch...

You just fixed my problem. Thanks soo much!
