It worked for me!

Had the following bugs (all related to each other):

• Download doesn't finished after 93k+ download, some missing files.
• If i tried to play, cannot update bug.
• If closed launcher, cannot find .inf file.
• If messed up with permits, cannot find/cannot execute pso2updater.exe.

The tweaker worked for me after doing the following (basically what they say to do on their page):

• Fresh install from WS (11GB).
• Update from tweaker (before even executing once the launcher, just do everything from the tweaker).
• After it finishes the 93k+ download, in the tweaker do to troubleshooting -> File Check -> New method. YOU MUST DO THIS! This is the step that will solve most of these problems.
• Start the lancher from the MS store. It will download 90k+ files, but it will go fast (you should see 1/2 in the lower part, once in reaches 2/2 it will say download complete and let you start the game).
• Done! Enjoy!

Thanks the arks guys!
