I'm just grasping at straws though. I know it is an incredibly frustrating issues and MS doesn't offer anything in terms of support for what is clearly a common issue with their OS. I had the same problem. I have been chasing this issue for a month and the fixes discussed here resolved the problem.
Specifically, stopping the service and deleting catroot2 folder. Thank you! Click the "Start" menu, and select "Run. Type " net stop cryptsvc " without quotations , and press "Enter" to temporarily disable the cryptographic service. Wait until the command line interface says "the cryptographic service was stopped successfully" before continuing.

I also noticed that prior to the host process error message popping up, a message stating that cryptographic services was failing to start popped up. Crypto is set to automatic in services and attempts to manually start it fail with the same messages as stated above.
I have attempted all the methods in the microsoft article on how to fix if programs won't install or update correctly. I don't know if it makes a difference, but in the microsoft article one of the methods lists reregistering dll's like initpki.
