Error code 0x80073D05; Windows Store cache may be damaged

I have been tried to install an extension for the Edge browser from the Windows Store, and I keep receiving the error code 0x80073D05.

That led me to try the Microsoft Windows Store Apps troubleshooter. It tells me that the "Windows Store cache and licenses may be corrupt.", and offers to reset Windows Store. After attempting to reset Windows Store, it tells me, "Windows Store cache may be damaged" and that it is not fixed.

Then I found some advice to run WSReset.exe in 'C:\Windows\System32' as Administrator. But I still received the 0x80073D05 error after this.

Finally I tried renaming the Cache folder 'C:\Users\<USERNAME>\AppData\Local\Packages\Microsoft.WindowsStore_8wekyb3d8bbwe\LocalState' to Cache.old, and creating a Cache folder. After that reboot, and re-run the Windows Store Apps troubleshooter, and it is supposed to now fix the corruption. But no, it still says, "Windows Store cache may be damaged" and that it is not fixed.

So all of that said, is there any way to resolve this issue. Or if this happens, is one simply out of luck? Only solution is to create a new user account, or reset / re-install Windows 10?

Thanks for any info!

Thanks for your reply.

I hadn't seen that tutorial yet. The steps I've taken I found through some Googling the problem... I'll take a look!
