I removed the windows app store for some reason. Then I try to reinstall it after removal, but it gives me error like this. I googled a bit but still cannot find relevant answers.

P.s. my firewall is okay and always running, so is windows updates. The services of both are running okay so it should not be the issues of these.

The answer is late, but I hope it will help someone. Had the same error today, but with the addition that the start menu wasn't working when clicking on it.

I could get it running again by enabling and starting the service "camsvc" (German: Manager-Dienst für den Funktionszugriff). It seems that the start menu is actually some kind of store app and needs that service.

Also the service provides the "windows.capability" and allows AppxPackages to be registered.

  • Then English name for camsvc is Capability Access Manager Service Dec 22, 2020 at 0:06

reinstall windows 10 and keep files. that'll do it.

  • This seems overly drastic, and worse, it fails to "solve" the problem but rather sidesteps it. Jan 1, 2018 at 16:21
  • i know what you mean. but this is a solution. it's not like i could use, turn it of an on as my solution for everything. this does specifically work if you've messed your computer up.

We are not picking on you, nobody is targeting you, it’s only about how helpful or unhelpful the answers you have been submitting have been.

  • OK, I must have accidentally taken a stupid pill this morning, because I do not see the emperor’s clothes. If the OP went from “State A” (Windows 10 with Windows App Store) to “State B” (Windows 10 without Windows App Store), and this (however arduously or drastically) gets them back to “State A”, how is it not an answer? And if I don’t understand your unhelpful comments, how do you expect this new user to learn anything from them? … … … And Ramhound in particular: if reinstalling the Windows App Store via an ISO is a good approach, how is reinstalling Windows (via an ISO) not equally valid?
