I'm trying to remove all traces of an old version of Microsoft 3D Viewer. These PowerShell commands say it's installed
Get-AppXPackage -All Microsoft.Microsoft3DViewerGet-WmiObject -Query "Select * from Win32_InstalledStoreProgram where Name='Microsoft.Microsoft3DViewer'"but it's not: I've uninstalled it and deleted all the files and registry keys I can find (even running regedit as SYSTEM). Where is this state stored please so I can hack it out?
Here's the output of those two, plus a failing Remove-AppxPackage. You can see there's no InstallLocation, and that it's installed for the SYSTEM user's SID (!). I've also deleted all of the keys that mention it in HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Appx\AppxAllUserStore.
The Remove-AppxPackage error is 80070057, which the troubleshooting page says is a bad manifest, but I'm not installing I'm deleting. There are manifests in C:\ProgramData\Microsoft\Windows\AppRepository, and I've tried restoring them from a backup but didn't make any difference.
