Hello,

I am encountering Error 0x80073701 while attempting to install certain features on Azure VM running Microsoft Windows Server 2019 Datacenter OS. This error appears when I try to install everything together or with each feature separately. Is there a way to solve this error without having to reinstall the OS, since it is a production VM?

    Hello

    "0x80073701" means "The referenced assembly could not be found".

    This indicates there is something wrong with the system component. Please open administrator command line and run "dism /online /cleanup-image /restorehealth".

    For adavanced troubleshooting, we could check the C:\Windows\Logs\CBS\CBS.log for more information (reproduce the issue again). There should be error message related to some components. Try to capture the process monitor log at the same time. We may get some missing components or corrupted registry keys. This may be complicated.

    If it is possible, it is recommended to open a ticket for Microsoft professional support.

    Or we could perform an in-place upgrade repair with an Server 2019 Datacente ISO installation media. Please make a backup before we made any modifications to the machine.
