Why is Blitz not detecting my League Client?
If you have a shortcut for League of Legends on your desktop, right click the shortcut and click Open the file location. If not, figure out where your League of Legends is installed and move to step 2.
Click into the path location at the top of the window. Once highlighted copy your full League of Legends path.
Now head over to your Blitz client and paste the path you just copied into the LoL game direction input box and Blitz is ready go recognize your team mates and you in champion select.
