Patcher not launching? Try this

I've seen numerous people having issues with the patcher not launching now, and I even experienced this myself. I was just doing some investigation into this, and found that the following fixed the issue for me.

Note: I do not know if this will fix the issues people are having with the program being blocked, but it may be worth a try. If somebody having that issues sees this and can confirm whether or not it works, that would be great.

And for clarity, the issue I was experiencing was that I would try to launch the patcher, the splash might show up briefly, but then it would just die off and do nothing. There were no error messages or pop-ups for anything at all. It's like the process just failed.

The Apparent Cause

I was trying to launch the game from a shortcut pinned to the taskbar. Turned out that running it from the desktop shortcut as an administrator would work, while the taskbar icon would not. I looked at the difference between the two shortcuts, and found that the Target and Start In paths were different between the two shortcuts.

My Solution

I made the pinned shortcut paths identical to those on the regular desktop shortcut. I also set it to run as an administrator, just in case.

Right click the pinned shortcut > right click 'LoL Patcher' in that menu > Go into Properties Right click the working desktop shortcut > Go into Properties

Copy the Target and Start In paths from the working desktop shortcut to the pinned shortcut (you'll notice the pinned shortcut has different paths). Then, just to be safe, in the Compatibility tab, check 'run this program as an administrator'.

Working perfectly for me now.
