Okaaaay… That’s strange, check for updates, then.
Let’s fix it!
This is actually a fairly easy fix, it’s just a little confusing. You’ll want to go to:
Help | Install New Software
And then add a new source:
These are the updates you want! So go ahead and update!
OH, come on!
Don’t worry! That error only happens if you leave “contact all update sites during install to find required software” checked. Simply ensure that you uncheck that box before you go through with the update.
And then you should be good to go!
