Black 4 Blood failed to launch: The procedure entry point

I suggest uninstalling the app completely! Everytime that it tried to give me a hard time I do this and it works wonders! Here are the steps!

Unfortunately this did not fix it

Hi there Nato welcome to the community forum! Christopher here, an Xbox fan just like you and has been on Xbox for years already. I would really love to make your day by helping you out. Is this the gamepass version?

I suggest you try these basic troubleshooting steps!

Open Settings, click Update and Security and then Windows Update;

Click Check for Updates;

Click the Download and Install Now option, if available;

Also, check the Microsoft Store for any updates on the Xbox apps and its services.

Then try this:

Go to windows settings > apps > search for gaming services app > click on it and select advanced options.

After that, click repair and then restore, open the app and try again.

Then do the same for the Xbox app:

Go to windows settings > apps > search for Xbox app > click on it and select advanced options.

After that, click repair and then restore, open the app and try again.

If it still doesn't work you're going to uninstall the games services using a powershell command, then you're going to open the gamepass app, it will ask you to download and install the game services again :

In the windows search bar type Powershell > Right click and select open as administrator > Type the command: "get-appxpackage Microsoft.GamingServices | remove-Appxpackage –allusers" > Wait for the process to finish and then restart the PC, then open your Xbox gamepass app, it will ask you to install the gaming services again, install it and try again.

I have this same error today installing Back 4 Blood. Both game services and back 4 blood fail like in the original post. I have not had any luck fixing it with any guide posted.
