I clicked on the update button when I was asked in Rig Manager. On start up it came up with a message asking if I would like an update. It went through all the downloading bar and then when it got to "Windows is preparing " bit, it just stayed there for 3 hours.
I had to cancel and then restart my PC from a shutdown. I tried this 3 times with the same result..............Not sure if Im the only one here???
that's an issue with your installation and the microsoft installer. you might want to remove rig manager entirely and download + update again.
