That didn't seem to make a difference unfortunately.
The first time I tried I noticed there were 2 suspended msiexec processes. I am unsure if they were running before I tried the commands you suggested running as administrator.
I rebooted and it seem to update windows. When I tried the commands again, nothing happended. When I tried to run the JustTrace setup - again nothing happened. There was no UI for it and I didn't get a crash message which sometimes happens with that installer. I tried the installer again and I got the crash message.
On another note, I got a message to update my CCleaner application by Piriform. I downloaded the setup (from here http://filehippo.com/download_ccleaner/download/946bb16ff8ce0569a852f4929a4b0e80/) and it ran fine.
I had a thought I was running from the Downloads folder so I copied it to another drive.
There is a compatibility checker in Windows 10 (never seen this before) which I ran - it tests the program. I've attached screenshot of the result. I will look at other things.
