Orchestrator Plugin missing after vcenter 7.0 u3c update

[VSprague]

I have an environment with Orchestrator 8.4.1  and vCenter 7.0. This morning I upgraded vCenter from 7.0 u2 to u3c and now the web client plugin for vRealize Orchestrator is missing and users cannot run workflows. How can I resolve this? I have run the "Register vCenter Orchestrator as a vCenter Server Extension" workflow from Orchestrator itself and that does not appear to have changed anything. Any help would be greatly appreciated.

I was able to resolve this issue by manually copying the vcoin-html-plugin to the recently updated vcenter server at /usr/lib/vmware-vsphere-ui/plugin-packages and rebooting the vcenter server. My users have tested and confirmed it is now working.
