I have an issue with a production server running Server 2012 r2 core and the Hyper-V feature with live VMs on it. The Hyper-V GUI mgmt tools and PowerShell modules are not installed and I cannot get them to install. It always fails with error 0x800F0906 suggesting I specify a source even when I use the /source: switch with or without the/LimitAccess switch.
I have tried running the install via DISM or the standard PowerShell Install-WindowsFeature commands.
I have even tried installing the whole GUI of the server but that fails too. Even when I specify a source.Install-WindowsFeature Server-Gui-Mgmt-Infra,Server-Gui-Shell
I have made sure the server has internet access.
I read that if you are installing from installation media that is the original disk then installed updates it can mean the media is effectively out of date so I have even injected all the applicable updates into a WIM and used that as a source but it still fails.
I looked through the CBS log and found a line saying “Exec: Not able to pre-stage package: package_4854_for_KB2919355~31bf3856ad364e35~amd64~~6.3.1.14” but I can’t really see why
Could it be due to a corrupt/unreadable package so it fails the install?
