Unable to create CAU clustered role - 2nd round

I have a 2 Windows 2019 servers in a failover cluster to share storage with the plan to add a few more in the near future. I had successfully setup the cluster aware updating role to this cluster in the past but learned that the application we were hosting had some compatibility issues with the clustered storage. I had removed the CNO and CAU objects and rolled back to stand alone storage.

The application vendor has since updated their program to work with the shared storage so I have re-established the cluster for these two servers with a new CNO name in the same sub-OU as before and they appear to be functioning well. However, when I attempt to recreate the Cluster Aware Updating role I am unable to complete successfully. I have pre-staged the VCO object (with a new unique name) in the same sub-OU as the cluster object and have reviewed applied the permissions so that the sub-OU has permissions to create computer objects, the cluster object has full permission over the CAU VCO. I'm using the same administrative account as before to setup the CAU the last time. This account has local administrative access to both nodes in the cluster and the ability to create computer objects in the OU where the cluster resides.

The error message I get indicates that it is unable to create the VCO: "Unable to create the CAU clustered role because a Network Named resource could not be created..." It is possible that this is attempting to create the computer object in the default AD computers container which I don't have admin access to. It doesn't seem to be respecting the command to use the pre-staged VCO object whether I run this from the wizard or from an elevated PowerShell cmdlet.

I would greatly appreciate any troubleshooting steps that anyone could offer. Thank you in advance.

    @Limitless Technology Thank you for the response Sridhar. You reference the ability to import settings from an updating run profile when setting up the CAU role or invoking a run.

    My question is why I cannot install the Cluster Aware Updating role to the this cluster? The goal is to set this up to self-update on a defined schedule.

    With the error message that is thrown when attempting the install, I don't see how passing additional run parameters is going to help?
