PC gamepass install issue 0x80070005

I understand your frustration, don't worry because we will solve it. I recommend you Clear the Windows Store cache. The Windows Store cache can accumulate corrupt or outdated files, which can cause problems when downloading and installing games. You can clear the Windows Store cache by running the following command at the command line (CMD) with administrator privileges: wsreset.exe

Additionally, you can perform the suggested xbox steps on this error.

If you're trying to use a game or app, uninstall it and then reinstall it:
Press the Xbox button on your controller to open the guide.
Select My games & apps > See all.
Select Games or Apps.
Highlight the game or app you want to uninstall, press the Menu button, and then select Uninstall > Uninstall all.
Reinstall the game or app by inserting the disc or downloading it again from the Ready to Install tab. To download again, select the game title from the Ready to Install tab at the top of the screen. You can also find the game by searching for it in the Microsoft Store.

The problem may be a little frustrating but we will solve it.
Check if you don't have any corrupt files in Windows.
1-Right click on Start and then click on Windows Powershell (admin)

2- Write these commands.
sfc /scannow (and press Enter)
Dism /Online /Cleanup-Image /ScanHealth (and press Enter)
Dism /Online /Cleanup-Image /CheckHealth (and press Enter)

3- The DISM tool will report if the image is in good condition, repairable or non-repairable. If the image is repairable, you can use the /RestoreHealth (Dism /Online /Cleanup-Image /RestoreHealth) argument to repair the image.

I'm sorry you're still having the download problem. You can restart the store and try the download again.
Open the Microsoft Store, click your avatar in the top right corner, and select "Settings." Scroll down and click "Reset" under the "Reset Store" section. This will reset the Microsoft Store and may resolve installation issues.

Always start as administrator. Right-click the Game Pass for PC installer and select "Run as administrator." This will ensure that the program has the necessary permissions to install correctly.

I have done that now, this cleared what was probably the corrupted file and let me start the install again.

Unfortunately I am still getting the error code mentioned previously.

I have tried to restart the download but the error code will flag up at any random percentage. As this is quite a big game and I have rubbish internet, it can sometimes happen within 5 minutes or 5 hours.

I had a similar issue with a different game but installing it to a different hard drive solved that. Doesn't seem to be working on this one though.

Hello ! My name is David, in charge of helping you today

I was analyzing your problem, and the first thing you should do in this case is make sure that your Windows operating system is updated. Remember that sometimes installation errors are corrected with system updates.
You should also verify that your computer has enough space to install the game.
We can also try to install the game but with the Antivirus disabled, sometimes the antivirus prevents the download of some programs, and you activate it after installing the game.

Best regards, David.
