Lately for most of my labs and even for many customers I have been deploying the VMware vCenter 5.5 Appliance, as it is much quicker to install and give less chances for error. Further it.
Browse to the location of the vCenter Server Appliance downloaded .ova or the .ovf file and click Open. In the OVF.

It is usually not required (ESXi 5.x works great with vCenter 5.5) but definitely recommended to Update the physical ESXi Hosts too. Additional components are required to be updated when you want to install vCenter Server 5.5: VMware vCenter Site Recovery Manager 5.5; VMware vCenter Orchestrator.
