Unable to Disassociate Host from vCenter

We recently were migrated back to our parent companies domain.
they decided to rename the server that vCenter was installed on and now it is a complete mess.
I want to uninstall vCenter and re-install on another server.  The current server is also the print server, hence the server name rename.
I found this post answered by Andrew on how to disassociate the Host from vCenter.

However mine only shows this:
If I click on it I get taken to the VMWare downloads page.
Also there is a note at the top that says the logs are stored on  non persistent storage (the old servername and domain)
What can i do?
Should i proceed with the uninstall anyway?
