Hello folks, I have a binary patch that will take you from V16 to V16.1 , and is only 45MB in size!.
This is for Windows ONLY and is 100% not official or supported, but with those caveats Chris has no objections to my sharing. I have used this for my own system, both at home and at work (:

Grab the V16_to_V161.exe binary , doubleclick and follow the prompts. There are MD5 checksums there as well for the paranoid.
Hopefully this works for Windows folks, but I'll try to help as I can.
