Windows server 2016 standard hyper-v installation error 0x80073701 RRS feed

  • Question

  • Dear Gurus,

    I am getting error code 0x80073701 while installing Hyper-V in Windows Server 2016 Standard edition. Here are the major error logs generated in CBS.log during service activation.

    • Package:      Microsoft-Windows-Foundation-Package~31bf3856ad364e35~amd64~~10.0.14393.0      [HRESULT = 0x80073701 - ERROR_SXS_ASSEMBLY_MISSING]
    • Microsoft-Windows-Foundation-Package~31bf3856ad364e35~amd64~~10.0.14393.0,      status: 0x80073701, failure source: Resolve, start state: Installed,      target state: Installed, client id: DISM Package Manager Provider
    • Package_7939_for_KB4565511~31bf3856ad364e35~amd64~~10.0.1.8      [HRESULT = 0x80073701 - ERROR_SXS_ASSEMBLY_MISSING]
    • Package_5940_for_KB4048953~31bf3856ad364e35~amd64~~10.0.1.3.4048953-12332_neutral      from file: (null) [HRESULT = 0x80073701 - ERROR_SXS_ASSEMBLY_MISSING]
    • Package_5940_for_KB4048953~31bf3856ad364e35~amd64~~10.0.1.3.4048953-12332_neutral',      rah = '2', manpath = (null), catpath = (null), ed = 0, disp =      0)[gle=0x80073701]

    DISM Cleanup-Image StartComponentCleanup & RestoreHealth and command sfc /scannow have been executed multiple times and output is also successful for these commands, however Hyper-V is still throwing same error code - 0x80073701.

    Request help on this.

    Thanks & regards,

  • 0x80073701 = ERROR_SXS_ASSEMBLY_MISSING which means there are some system files are missing, which caused the installation failure. You can also try a repair install by running setup.exe from the root of the install.

    I wouldn't hold much hope for this, better time may be spent standing up a new one, patch it fully and migrate the roles or applications over to it.

  • According to the information below, there is a lack of files, so it is likely that an error has occurred.

    Check the CBS log files and copy the missing files from the appropriate machine and it seems to work.

  • I went through these steps and checked KB4565511, the updates were already installed in the system. I even uninstalled & installed again however getting same error. KB4048953 refers to year 2017 and its replaced by this KB4565511 which is already installed as part of July 2020 auto updates from Microsoft. Rest no other issue as per CBS log but cant proceed with Hyper-V installation due to error code - 0x80073701.

  • Hello ca.nikhilsinghal,

    If the cleanup image did not do the trick, I would run a chkdsk to make sure you do not have corrupted disk media.  If chkdsk does find media errors, run it again using the /r switch then re-run the DISM reimage.

    The best thing to do is what's mentioned by Patrick which is to start over with a fresh install. Before installing Windows, you may want to run a full disk initialization on your RAID controller so that any disks that have media errors are identified. Better now than later to find any disk errors.

  • It's a live system so creating from scratch is not an option available to us at this point in time. I think sfc /scannow also uses same repair technology as available with setup.exe, however we will try running a repair install. Meanwhile if there is any other option we can try, please let us know. Please also let us know if we can identify the missing files and it can be replaced from a reference machine.

  • What else is installed? It isn't recommended to run other roles / applications on a hyper-v host. Also for Standard edition this takes away one of the two guest Operating System Environment rights.

    Debugging windows servicing is beyond capability and scope of forums support. I'd suggest starting a case here with product support.

  • Just ran chkdsk and no errors reported - Windows has scanned the file system and found no problems.

    SAP is installed in the host and we need just one VM to take care of main installation requirement so we are good from standard edition licensing requirements. We will carry out a repair option during a downtime window tomorrow and in case error persists, then shall raise a support incident.

    Thanks a lot for the prompt response and help on this.

  • Hello Dave,

    We were able to activate Hyper-V feature post executing repair install from fresh Windows Server 2016 ISO setup.exe. It was a big piece of work including all sets of following updates however finally its done. Thanks a lot for your inputs and timely help.

    Thanks & regards,

    Nikhil
