Yeah my issue is that MS STORE refuses to install PSO2 to the previous drive where it was working fine. But it can install to my system drive which lacks the space for it.
Converse with fellow players
It should be in a hidden folder called WindowsApps on whatever drive it was installed on, which is a pain in the ass to access. I was able to get into it with this guide and clear out most of the wasted space after two nuked installs, though about 10gb worth of crap still remains that I still can't permissions for even with this program.
Edit - as of now it will continue to move the game to this folder, requiring a re-download every time the computer resets, sometimes even without, until Microsoft manages to fix the problem on their end. Even using the tweaker (https://arks-layer.com/) this still happens for me.
Good stuff my dude, this is what they gotta sticky!
Managed to scrub PSO2 off my PC and I think it recovered all my storage space. Tried reinstalling again and game still refuses to launch.
Guess its farewell to PSO2, had fun while it lasted shame the game is crippled by quirky distribution systems.
