  4. Can you both please check that your vCenter Server and vCenter Management Services are running as “Local System”, and and not .\Administrator?

    They should run as “Local System” to avoid such issues.

    If that does not help, is there any other error message in vminst.log?

  5. Sorry for the dumb question but does this require a full reinstall of vCenter and components or is it more of a patch you run against your existing installation?

    • There are usually no “patches” or “updates” for the vCenter Server. You always download the same full vCenter image. When you start the installer, it detects that your system already contains a versions of the vCenter and does an update. If it does not find anything, it does a fresh installation. If it finds the same version, it goes into “Remove/Repair” mode.

      The update is in most cases a click-through nobrainer.
