After failing to apply an update to Adobe Air, I attempted to re-install it from scratch. This is at the end of the installation log:

The log covers many attempts. The latest was on 29th September.
Following a suggestion in another forum thread, I checked the file permissions for folder 'c:\users\martin\appdata\local\temp'. As far as I can see, they give full control to the SYSTEM, administrator and sole user (martin) accounts. There are no options with 'Deny' against them.
I have run Microsoft FixIt. I also tried the Windows Installer Cleanup utility (msicuu2.exe) but I got 'Access Denied' with no further details.
Any suggestions?
