Attempting to update VCenter from 5.1U1 to 5.1U2 and starting with the SSO server. When kicking off the install it immediately advises “Another version of this product is already installed. Installation of this version cannot continue. To configure or remove the existing version of this product, use ADD/Remove Programs on the Control Panel.”
Surely one doesn’t have to uninstall SSO simply to upgrade it? Anyone else experienced this or performed the upgrade from U1 to U2 without incident?
