Brad,
All versions should be automatically put into the Download Folder. Just move them to Trash. You can search for all files named MSAutoUpdate and delete these too.
I have checked my current version of 3.4.0 - It is dated 5/1/16. The new one mentioned by Anneliese is 3.4.0-160315 and dated yesterday - 18/3/16.
Here is a brief Page History of all of the messages in this thread:
P1 Discusses to DNS Workaround. Don't forget to delete all existing addresses in the DNS Folder before adding in the new ones.
P2 Suggests a Router Shutdown - wait a few minutes - and then reboot. Too many people are in too much of a hurry and do not give enough time for the current to dissipate from all of the circuits before powering up again. I tend to leave it for a good 10
minutes (Tea Time!)
P3 Details the DNS Setting method
P4 Has detailed actions that I carried out on my MAC to get it to Download successfully. This included shutting down the MAC - waiting a few minutes (Another Tea Break!) - and rebooting the MAC into SAFE Mode before running the pkg file again.
P5 And around the Buoy we go again!
Hope this helps!
Dave
