Moderator: Thread moved to the vSphere area.
If youre looking for the windows based vsphere client your way to late dude..... its gone ages ago. VMware now offered browser based GUIs and with 7.0 the flash based browser version is dropped. The former HTML5 Client is now the vSphere Client.
You have to create a Datacenter object in the upper left and than choose "Add Hosts". Nothing changed there in the last 15 Years.
