Well... I just had a MS update overnight, even tho I specifically told Windows to not do this. Aaaand it f-ed up my PSO2.
After update overnight, PSO2 won't launch. At all. No error whatsoever, just won't launch.
I've tried Repairing the PSO2 app but it does nothing.
Neither does Reset.
I've tried restarting my PC.
I've tried restarting MS Store with the wsreset.exe thing.
I've tried taking Ownership of the folder in WindowsApps to see if anything is wrong with PSO2 and I discovered that the PSO2 on MS Store is split in three pieces. That would be rather upsetting on its own. The app folder itself, Oxyna can't be changed at all, even with editing registry.
There are two other Oxyna folders in the Mutable folders, the one that can't be accessed even with Take Ownership is what I assume NA version... lite? Translation.
100B7A24.oxyna_220.127.116.11_x64__wyfsmff9ynw7j is what I'm talking about. That seems to be the NA-lite.
Meanwhile 00B7A24.oxyna_18.104.22.168_x64__wyfsmff9ynw7jee3fc0b8-e17c-4b99-b9a6-1d9d8a4eed55 seems to be where the game actually is. Launcher here connects to JP servers, I can tell by the news slideshow which shows content that is right now relevant in the JP version, while NA lags behind as usual.
Considering those two folders, I can take a good guess that the game is actually in the 2nd folder, as it has over 50GB, while the 1st folder has only 10GB.
But either way, this seems to be a total Windows Store meltdown. There doesn't seem to be a fix. And I just wanted to play some PSO2 before dentist... Sigh.
EDIT: After two hours of cycling trying to Repair, Restart, annoying MS support on Twitter, and trying every other way mentioned online, I just got my first error message during fourth? Repair. That I don't have high enough Administrator rights. To note, I'm the only user and administrator of the PC.
EDIT2: Screw it. Just gonna do it through Tweaker.
