SketchUp 2016 is here!

My new friend, Tommy, led me to a copy of Make 2016. Thanks, big guy! Unfortunately my install failed with the message, “Could not write to key
\Software\Classes\style.Document\shell\open\command
Verify that you have sufficient access to that key, or contact your support personnel.”

I tried running the setup as Administrator and it still failed. I ran multiple malware and virus cleaners with no change. Perhaps Win7 Home Premium is no longer adequate? I’m definitely getting discouraged. Any insights, hunches, or casting of spells would be appreciated…
