Rhino 6 update will not install

I am currently running version 6.4.18124.12231 from 5/4/18 and when I start the program it says an update is available. When I click on it it takes me to another Windows dialogue box that asks me if I want to install it. When I click “yes”, nothing happens. I have tried several times (I am logged in) and nothing happens.
Any suggestions?

I’d suggest downloading the current V6 “full” installer and running that:

Any luck?

Thanks. I’ll give it a try and post back.

That worked. Tanks.
