From where do I manually download updates

Since the auto update will not work properly since installing and reinstalling (twice) V3
(starts then quits about 5% into the download and tells me to check my connection despite there definitely being a connection)
what is the link to manually download the updates so I may install them myself.

Searching did not turn up a link.

You cannot download a patch or just the updates. Have you tried a complete uninstall and reinstall of the latest version. If you download and install the latest version then you will have all the updates.
