I'm trying to help a friend install Pso2 using the tweaker, but whenever he downloads it and tries to update the tweaker, he gets an unhandled exception error. And when he tries to click continue the program hangs. We've tried running it as admin, downloading the updater manually, deleting everything and re-downloading, but to no avail.

My friend is running Windows 10 64 bit, and has .net framework 4.0 installed.
