Unable to install patch 3.26.0i

I don't know what's wrong, I've never encountered this issue before in all my years playing PoE. The game simply won't go through with the patching regardless of how many times I try. And yes, I've tried rebooting my system. Still doesn't work.

Edit: Fixed. It went through after I opened the client inside the game folder rather than the desktop shortcut. Weird stuff.
