[NAME]  Have you tried rebooting your computer, and then disabling your anti-virus/anti-malware application(s)? It/They sometimes interfere with installing updates and components. I hope this helps.  Have a great day. Regards,-Phil
I have been trying to let the support assist recovery to install for the last two days.   I  click install and the whole support assist window goes grey and says it is validating but it never goes any further.  I am not sure what to do  ugh 
Support assist os recovery hangs at the install point
