Cisco vWLC deployment in ESXi 6.5 Bug - "A required disk image was missing"

A marginal side track but still semi-relevant...

I tried to deploy an OVA file of the Cisco virtual WLC (vWLC), and I've tried a number of the versions and I keep getting the same error... - A required disk image was missing

After a little googling it appears to be a known bug, Cisco vWLC doesn't like being deployed on EXi 6.5 via the ESXi web interface. There seems to be 2 workarounds:

• Deploying via vCenter web client
• Using the OVF tool

I've tried the installation via the vCenter web client and I can confirm this works fine. I've not been able to try the OVF tool yet.
