An update is perpetually available

I checked for updates yesterday morning and saw that Rhino was downloading a new version and was at 40% or so. It appeared to download extremely slowly and I went ahead and downloaded manually. And installed manually.
Now, Rhino keeps saying that An update is available.

When I click “Install Now…” upon exit, I get a “wait for configuration” box but it seems that Rhino figures out that that version is already installed and nothing more happens. When I then launch Rhino again, I get the same update message.

Yeah, getting this too here… --Mitch
