Why don't you patch the host from the command line using the latest .zip Offline Bundle?
To do this, upload the Offline Bundle to a folder on a datastore, and run the above mentioned commands:
1.) Find out the profile name
esxcli software sources profile list -d "/vmfs/volumes/datastore1/<Bundle>.zip"
2.) Update/patch the host (after shutting down the VMs)
esxcli software profile update -d "/vmfs/volumes/datastore1/<Bundle>.zip" -p <Profilname> --dry-run
Note: "--dry-run" is optional, and shows what the command will do, without actually doing anything.
Once the update command succeeds, type "reboot" to reboot the host.
