Xbox (beta) PC - error 0x80070005 while downloading

In this thread there is the fix:

Cannot download GamePass PC games through Xbox Beta App, with error 0x80070005

Dear Community,

I bought game pass beta today. I have a problem with games that need acceptance by administrator. When i try to download them, there is an information about an error 0x80070005.

I have Windows 10 up to date. I am log in into administrative account (there are no other accounts). I try to help myself for hours (google tips and Microsoft forums) but nothing work for me.

Thanks for advices!

If your Microsoft account is set as under 18 that may be why.

Been having this problem since launch, you can try some of the fixes posted here like :

But I tried alot of them and nothing seems to fix it...

They STILL haven't fixed this????

I (along with many others) had this exact problem in June!

I just got a code I can redeem to try another month but if this is still happening I don't see the point

This was fixed.

But the error came back some days ago.

I tried everything what was on the internet and nothing worked. I didn't want to format my PC. The solution was to set TrustedInstaller as the owner of the folder WindowsApps (folder where Game Pass App or Windows Store App install all Apps). You have
to set it on each drive if you have apps installed on different drives. Right-click on the folder, then "Properties->Security->Advanced" and you will see the owner there and you have to click "Edit" and on the empty field you just paste "NT SERVICE\TrustedInstaller"
without the quotation mark, then you click "check username" and the TrustedInstaller should be underlined and you hit "Apply" and then "OK" on all windows. You do that on each drive you have the folder on then you restart the PC and it should work
