Svr 2016 Standard- can't install roles - Cumulative Updates fail.

[jc07874]

This is a new installation of a server 2016 system (being installed to migrate a server 2008 R2 domain controller to the New 2016 Server.
The AD and DNS installed without a problem. AD Is replicating and DNS is working as expected.. Windows updates were ran as some point. Everything was looking good. FSMO roles are still provided by the old server.

But now trying to install DHCP server roll getting an error " The referenced assembly could not be found. Error 0x80073701.
Also Failing the 2018-10 Cumulative Update for Windows Server 2016 for x64-based Systems (KB4462928) - Same error

DSIM passes SFC says there are errors and assembly is missing .. Says it repaired them but doesn't fix anything.

I uninstalled the unneeded language packs thinking that was the problem.

No Joy! Error persists. ​

I did not modify any of the registry items manually.

Here is the CBS log which includes the last DHCP role install attempt.

Here is the CBS log file after running SFC Scan

Please help.
Let me know what else you need.. Luckly this system is not in production yet.

Thanks .

Hello and welcome!

This is an extremely hard problem to fix. I'm currently trying to fix one, and I am not sure I'll be able to completely fix it, however, I can fix SFC and get you up to date if you wish. After we have accomplished that, we can try and solve the roles issue if you'd like.

Please let me know.
