I downloaded VMware-VIMSetup-all-5.0.0-639890.iso and mounted it to my vCenter server. I then proceeded to upgrade the Server, Client, and Web Client components. However, even after a successful install and reboot the reported build numbers in Help > About vSphere have not changed. They are still being reported as the previous version: 623373.
The installer(s) recognized that an upgrade was going to be performed. I tried running the installer(s) again and they are asking to modify or remove the installations. Clearly the upgrade installer(s) has done what it was meant to do.
How is it that the product has not actually been upgraded?
