    AppLocker Blocks Windows Store Apps Downloads

    Hello --

    I've Windows 10 Pro x64, and I did a clean install a few days ago because of a similar issue.

    Now, Windows Store does open up and installed apps run just fine; however, I'm not able to download new apps or update existing ones. Downloads get aborted with error 0x80073CF9.

    Event Viewer returns the following...
    Log Name:      Microsoft-Windows-AppXDeploymentServer/Operational

    I've tried setting AppLocker to allow all signed packages to no avail. I've also tried "WSReset.exe" which doesn't seem to do anything. Further, I've created an "AUInstallAgent" directory under Windows.

    I believe it's a permission issue, because PowerShell throws an IOException error; therefore, I've tried changing permissions on various folders. I'm lost.

    Please advise.

    Had to reinstall the OS.

    I think the problem was that permissions didn't propagate thoroughly when I changed the name of my computer.
