did you install VUM? the installer is on the vCenter media under the vpx folder. If you have installed VUM, you need to download and install the plugin, which can be found in your Plug-Ins Menu.
thanks for the quick reply.
i dont have the vCenter media is this something i can download?
Update Manager requires vCenter, so without vCenter you cannot use VUM. You can download a trial for 60 days.
