Fan-made tool helps fix Phantasy Star Online 2’s broken Windows Store launch

PSO2 Tweaker already works with the official release of the game, and it's fixing many of the issues early players have had

If you’re looking for a Phantasy Star Online 2 PC fix, it seems the game’s long-standing mod community has your back. After a ream of issues with the game’s launch through the Windows Store, the popular PSO2 Tweaker tool, which has helped English-speaking fans play the Japanese release of the MMORPG for years, is now compatible with the new, official release – and seems to be fixing many of the problems reported at launch.

PSO2 Tweaker essentially replaces the game’s standard launcher and updater. You still make an initial download of around 10GB through the Windows Store, but you can use PSO2 Tweaker for the remainder of the massive, 80GB game. Neither the Windows Store nor the default launcher seem to be wholly responsible for the game’s early issues, but either way, the PSO2 Tweaker offers a fix for many of those problems.

You can grab PSO2 Tweaker from the main site – make sure you follow the setup guide to get it installed correctly. The issues players have been running into have been too numerous and varied to list here, and the new launcher won’t be a magic bullet for all of them, but it just might help.

On Discord, the PSO2 Tweaker devs add that “many cases of the game nuking itself are caused by installing the game to a drive other than the one Windows is on. When you reboot (or sometimes quit), it tries to do silly Windows Store stuff and breaks the link between the game folder and the store, so the store thinks it’s corrupt and nukes it, asking you to reinstall.”

The devs are currently working further updates for PSO2 Tweaker, “including attempting to bypass the Windows Store completely” – though given the game’s integrations with Microsoft’s servers and Xbox Live, that might be a difficult feat.

On the official side, the PSO2 devs have confirmed they’re aware of the issues and looking into solutions. The devs say more announcements are coming “soon”.
