Sea of Thieves "Launch Error. Unrecognized game client. Cannot continue."

Hi Hunter.

My name is Renato.
I'm an Independent Advisor and a Microsoft Xbox user like you.

I inform you that here in the community, we are all users and do not have access to your data and account. We can only offer you advice based on our knowledge and experience.

I understand that after various attempts, you're tired and somewhat disappointed. However, as you mentioned, your friends reinstalled it and it works for them, so it seems the problem is local to your PC. Unfortunately, system errors can occur, and sometimes a Windows reset or a clean installation might be necessary.

Before considering these more drastic solutions, I recommend trying to reinstall the Game Services. Before proceeding, it's always important to check that there are no pending Windows updates and to ensure that the Xbox app and Game Services are also up to date.

To update Xbox app and Game services

Press the Start button on the taskbar, type store, and open the Microsoft Store app.
Select Library.
Under Updates & downloads, check if there are any updates available for the Xbox app or Gaming Services app. If an update is available, select Update.

To remove and reinstall Gaming services.

Press the Start button on the taskbar,
type 'powershell,'
right-click on Windows PowerShell, and then select 'Run as administrator.'

In Windows PowerShell, type the following command and press Enter:
get-appxpackage Microsoft.GamingServices | remove-AppxPackage -allusers

In the same window, type the following command and press Enter:
start ms-windows-store://pdp/?productid=9MWPM2CQNLHN

Install the app on that page and select 'Yes' when you receive the User Account Control (UAC) prompt.
Restart your device and try to install the game again.

I hope I've been helpful.

Kind regards
Renato

On the Microsoft Store I cannot see Sea Of Thieves, I can only see it on the Xbox Client, but I can see the download on Microsoft Store, even the error.

If you're trying to play the Xbox Insider version of Sea of Thieves, then be aware that this was the closed Beta before the game launched.

Unless they added an Insider Version after I checked two days ago, you can't play that version, as the servers don't accept the Sea of Thieves Beta client anymore.

You will have to buy the actual game, or have an active Game Pass subscription to be able to play Sea of Thieves.

Also the problem with the game not installing is only for sea of thieves but for other games they get installed but when I launch them it pops up with the error code 0x803f8001 while for sea of thieves it pops up when I try to install the game.

It says it cannot move sea of thieves and gives me the error code 0x80073d0d.
