@Neoyoshi Aready had an xbox live account. windows 10 64 bit, version 1909, latest update, newest .net update, Microsoft Store preloaded permanently on system, and up to date (Indeed, the laptop was recently purchased, and thus I spent a good two days going through all the updates, until there wasn't a single one in need. I made sure to meet all the requirements, and in fact, bought the laptop, specifically so I could play PSO2, as I'd been waiting for its NA release for a long time), xbox companion imnstalled, MSI GS75 Stealth Gaming laptop, 9th gen i7 intel, all system requirements excede minimum, and recommended for the game. Xfinity/comcast internet provider with High speed internet, living in North America, East coast. Double checked all updates the day before release, installed on C drive, by default, let Windows Store handle all the install locations, no 3d party download managers or game launchers, in fact, the game installed and worked fine the first day. I played it for about 8 hours. Then went to bed. Next day restarted my computer, and the game wouldn't start. Clicking on the shortcut, the start menu tile, tried launching it from windows store, wouldn't start it. Then saw it was reinstalling. Waited for it to finish reinstalling. Played again. Game plays perfectly, love the game. I let my laptop restart the next day. Same problem as before, then I realize I've lost over a hundred extra gigs of hard drive space on top of the actually game itself. I can't figure out what happened. I figure maybe there's an update for windows itself running in the background, waiting for a restart to finish installing. I restart, hoping that fixes things, and now the game installs again. I opened system app, and attempted to repair the game in case it had been corrupted somehow. Nothing happens. I attempt to uninstall it. Nothing happens. I try uninstalling it with the pso2 uninstall, nothing happens. I try to stop the install, can't. Games still stuck in download loop filling my hard drive. I remove the game program itself from the un-hidden modifiablewindowsapps directory, which prompts a correct re-install (the game icon actually shows itself as in the process of installing. It hadn't before). After this reinstall (which still eats up extra hard drive space, beyond the game itself), I'm able to uninstall the game. I uninstall the game. Game files are gone. Game is gone, all the downloaded game install files in the hidden folder however remained. The uninstall didn't remove any of the multiple copies of installation files for pso2. Next to no hard drive space remaining. Go online, and learn how to access the hidden folder, and remove the install files manually, since the Windows Store has no option to uninstall the game or the installation files, available. I remove the files, and only those files. My computer has it's hard drive space back. I'm now waiting for a solid consensus that the problem is fixed before trying to install the game again. Wish I had a problem free experience like yours. Being able to play it for two days and truly enjoy the game, having to remove it in order to save my computer, doesn't really make me happy. I want to get back into the game, but I'm patient enough to wait until it's safe.
