Weird, I guess they just didn't update the version mapping.

You have the Windows-based vCenter there. You ideally shouldn't be installed a new vCenter on the Windows platform as this is a dead end and will not continue after this version, not to mention there are a whole host of features it doesn't support. The only thing you should be installing anew at this point is the vCenter Server Appliance (vCSA) which can also be found on that downloads page.
