Which OVF file for FortiRecorder

Looking to install FortiRecorder. Downloaded the zip file and have several ovf files in which to pick for install. Running vSphere, documentation states to pick your associated ovf file. In the list, I have Fortirecorder-vm-64bit-hw10.ovf, hw13, hw14, hw15, then hw10.e1000.ovf, which I assume is using the e1000 NIC.

Any pointers? I would contact support but it doesn't seem I have an entitlement to this purchase so I am running with that to the VAR.
