@Tigris1701 Found a solution for the lag! go to pso2_bin folder rename the pso2launcher to keep it as backup, like "-pso2launcher" copy the pso2 file in another folder like gameguard folder, rename that pso2 file to "pso2launcher" then cut it back on the main pso2_bin folder. That bypasses the launcher, straight into gameguard splash, I'm having zero lag in the lobby now.

Also another thing I did, so don't know which was it that fixed it, but based on comments, the one above.

go to windows settings> system>display>graphic settings> universal app> select phantasy star online and put it in high performance.

I'll try to summarize my experience to see if it can help someone, as I myself was in a similar situation of frustration and not understanding what was going on.

First I want to clarify why I had to re-install windows 10. That was me on the first day trying to delete the game, and all folders installed that day from the game (Most of the inside windowsapp folder) and then ended up deleting things I needed for some of my apps to run, and they would not work after re-installing them, hence my option was a fresh windows start. be very careful to what you delete inside the windowsapps.

If you don't wont to try anything until there's an official fix, follow most of the tips on link text after you delete everything on your PC, you might still have less memory in your drive. Right click on it, properties and do a disc clean-up. Also if you have CC cleaner or similar, run it on your registry and fix entries made by the game, since the files are gone it will delete the game entries.

This is what I did after my fresh install of windows 10

• downloaded xbox companion app, went to MS store and added the game to a cart, then checkout (for 0$) and then launched the MS store app to install the game. The checkout and add to cart will help to get privileges on the game and I read solves some issues while downloading or trying to install it ( don't go to the store using "get" option)

• First time around I installed the game on my SSD C :, which is my main drive for the OS, 500gb, 320gb empty space. everything fine, launched the game and same game guard loading and then nothing happened. I tried the fixes like using powershell as admin and add the lines of code for access, and also tried the privileges on the pso2 folder. Same result after game guard. Uninstall the game, with no problems this time, and no leftover files or space being taken on my drive.

• Second time (or more like 5th, but 2nd since fresh windows10) I decided to install the game in my secondary drive, a HDD. It created the same folder, even some in C :, as I explained here link text. Did the powershell admin lines of code, and this time I tried it on both folders pso2_bin, which worked fine, and the oxyna folder directly under windowsapps, not the one under windowsapps>mutable>oxyna. That one didn't let me, powershell kept giving an error saying access was denied. Launcher finishes downloading, Game works!.

cd "D:\Program Files\ModifiableWindowsApps\pso2_bin"

first, then one line at the time

Get-Acl pso2launcher.exe | Set-Acl pso2.exe Get-Acl edition.txt | Set-Acl otp_notice_na.rtf

• Closed the game by mistake, then I couldn't open it again. back to square one. I opened the launcher again, while it was open, not doing anything, I went ahead and changed the permission manually of the pso2_bin (since I could not do it on the oxyna folder) using the post AccelShift gave, getting ownership of the folder, making sure all the files inside inherit the privileges, then not adding a new permission, but editing 2 existing (second from the top between 2 that have full control, and the user under the one called RESTRICTION) clicked start game and it must have taken 1 or 2 minutes after splash was gone, and the game suddenly started. No errors from there onwards. After start menu, xbox companion window opened and selected my user.

• Closed the game, and when trying to launch again, launcher was in JP... and this time wouldn't even get game guard to open. Check files again, while launcher open and done with the check, went to the pso2_bin, did exactly the same thing, and this time I went inside to the notice.txt (opened it and it says NA, but keeps launching in jap, meaning the launcher can't access the file) this time I added myself to the privileges of the notice.txt file. Closed the launcher, opened it again and back to NA, and game was working again.

I'm not saying this will work for everybody, but if you were in a similar place, and have the spare time and try it around, like I did, go ahead, I've seen a lot of people commenting "this doesn't work for me" or " this doesn't help me", well then that comment also doesn't help anyone... maybe your problem is other, go to reddit, there is a mega compilation there if issues and fixes, same in discord. Maybe you can find a solution, or an idea on how to fix it there.

@Kid-Sizzle You need to have the xbox companion app logged in with an account, that's how the game gets your ID

@Tigris1701 Hey! it's weird, I did log out of the game with the log out option. Tried to start the game again and launcher was in JP, my fix for this was going to pso2_bin folder again, while I had the JP launcher open, I gave myself full control of the edition.txt file, close the launcher, start it again and now I'm back in the game

It is horrendous the lag in the lobby and the shopping, what ship are you on @Tigris1701 ? Solutions i've seen for lag, that I'll try now are, setting on my NVIDIA control, the GPU as the preferred processor, and also select pso2 to run on the GPU. In game you can also disable the playback videos from the lobby on the settings. which I'll do now

Edit for FPS: definitely an improvement after doing that, considering I'm in ship 2 and it's showing full on every block, FPS is better than earlier when it was half empty.

This is so bizarre... After my last post, I did the privileges on the file again, spent the whole day playing, afraid of closing the game and not be able to play again. Finished just now, and wanted to see if the game will start again, and now I get the Japanese launcher, and not working again

Holy mother! it works!! I'm in!

I feel like crying... All I did was installed it in my HDD drive instead of my SSD, and follow the reddit fix for .dll mising files Using powershell as admin

cd "D:\Program Files\ModifiableWindowsApps\pso2_bin"

first, then one line at the time

Get-Acl pso2launcher.exe | Set-Acl pso2.exe
Get-Acl edition.txt | Set-Acl otp_notice_na.rtf

EDIT :Closed the game by mistake, now stuck at the same thing... not launching after GameGuard...T_T

@HoDKenji have you tried right click on your drive, properties, disk clean-up? Also if you have a software like CC cleaner, would be nice to run it, as it will also clean the registry

On today's adventure... I'm trying to install the game on another drive. So far the "windowsapps" folder has been created on the specified D : drive as told on the MS store, but obviously now is asking for permissions to enter the folder, which for funsies, I'm not gonna change. In the C : drive "windowsapps" I have both C : \Program Files\WindowsApps\100B7A24.oxyna_1.0.7.0_x64__wyfsmff9ynw7j and C : \Program Files\WindowsApps\Mutable\100B7A24.oxyna_1.0.7.0_x64__wyfsmff9ynw7j but they show as shortcut Icons to the one in D : drive, it also allows me to access the folder.

Edit: It has also created this folder in the D : drive D:\Program Files\ModifiableWindowsApps\pso2_bin so again, I have two copies of the game, which I imagine one would be JP and the other NA

@manodalvizin I'd love to not touch it until fixed, but I'm on lockdown, and I have nothing better to do so I'll keep trying, worst case scenario.. I reinstall windows from a backup, as I did yesterday.

@AccelShift , and @Tigris1701 , thank you both for the tips. I tried them yesterday and neither worked for me, if you are still playing. DO NOT RESTART YOUR PC, it will delete some files of the game.

I'm going to list here the errors I encountered yesterday, during my 13hrs trying of installing the game, and although I posted my experience in a rough manner in another topic, "game won't start after game guard", in which I believe 3 or 4 people only encountered that problem and manage to make the game work with things that they posted there. So if you are having that problem, go and have a look at their solutions, gods might be on your side, and you might be able to make it work.

Also one thing is confirmed for people who gets the game working restarting your PC will delete files of the game

So for Devs or GMs I've decided to explain in more details what the game is doing in most of the cases.

• The moment I click on Install at the MS store, the folders "windowsapps" (which is normally a hidden folder and will need to grant permissions to open) and "modifiablewindowsapps" are created under, in my case C, for short from now onwards I'll call them "wa" and "mwa". Inside "wa" I get the famous "oxyna folder", and inside "mwa" nothing.

• When the game is ready I launch the Phantasy Star Online 2 icon on my windows start menu, and the NA launcher comes up, it says that it downloaded the latest version of the updater, in which I can only press back, then starts downloading the game. Now the folder "pso2_bin" is created within "mwa" folder, and the folder "mutable" is created under "wa". In the case of "mutable" I find inside, what it displays with the icon of a shortcut to a folder, oxyna folder once again, but with the same files that the "pso2_bin". So if at this point I open the oxyna folder, directly under "wa" the files that it contains is lesser than the actual "pso2_bin" and also none of the .exe files has the icon of pso2, just a standard .exe icon, but if I access any of the other 2 mentioned folders created, there are more files, and all of the .exe have the pso2 logo.

• Downloading is finished (Oh lord thankyouforyourblessing because I'm ahead than most people) so I go ahead and click "start game" red giant button of glory, launcher closes, PSO2 logo in the centre of the screen, and on the top left corner GameGuard starts updating, finishes without any single error, then just the PSO2 logo, and then... nothing, under task manager the task just closes itself. (This is the original "game won't start after gameguard")

• Since there are so many folders with pso2 files at this point, I went ahead and decided to manually open them from the folder, and here is my favourite part, when going to "mwa">"pso2_bin">pso2launcher right click open as admin, a completely different logo opens and the JP launcher starts! whit my basics of japanese from the golden era of PSO2 JP 4 years ago, and also but this point knowing what each button does by memory, I click start game, and immediately after I get an error saying that "d3dx9_43.dll file is missing". At this point I'm committed to play even if its in JP, so I re-install my DirectX drivers, launch the game again.... nothing happens, not even GameGuard opens.

• If I try to open the launcher from the "wa">oxyna folder, it straights tells me I don't have permissions, even though I granted myself all the permissions of the world, over "wa" and all of the contents within, future generations will bow to me, AVE CEASAR!, it won't let me modified the permissions of the oxyna folder, nor the launcher inside.

• If I now try to open the launcher from inside "wa">"mutable">"oxyna folder", NA launcher chan appears again, click "start game" now again no GameGuard part, just a famous error about the "vivoxsdk.dll" appears, and sorry at this point I didn't even tried to fix this, just uninstall everything and went to bed.

Sorry for the long post and the lack of potato.
