Adobe AIR installation on Vista. Message: 'An error occurred while installing Adobe AIR. Installation may not be allowed by your administrator. '

Question

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?

Answer 1

I have managed to edit the Registry so as to get the Windows Installer (MSIExec) to write a verbose (detailed) log.  From this, and some web forums, I found that the problem has been caused by a Microsoft Windows security update, KB2918614.  This was applied on my PC on 14 August but I think it was released on 12 August.  My Windows version is Vista and I don't know if this update or a similar has been applied to other Windows versions.
For more information see wix-users - SECREPAIR: CryptAcquireContext: Could not create the default key container.
I went into Windows Update on my Control Panel and found how to uninstall update KB2918614.  When I had done this, followed by a Restart, I was able to install AIR and the software that uses it.
