Hi Chris
I have the problem identified above sadly Microsoft no longer support the Fix It solution. The appropriate lines from my log are as follows:
[2016-07-25:21:53:23] Relaunching with elevation

[2016-07-25:21:53:26] Runtime Installer end with exit code 7
[2016-07-25:21:53:31] Runtime Installer end with exit code 7
The applications I use which use Adobe AIR still work OK but every time I use them I am offered the Update process which always fails so is somewhat annoying.
Hope you can help....
