Visual Studio 2008 fails to install redux

I wrote the other day about the hack I used to get Visual Studio 2008 SP1 to install. It was to overcome the problem with the VC++ run-time always failing to update.

Further research has revealed the actual root of the problem and a way to fix it.

The registry keys for the installer components for the VC++ run-time have the permissions borked. Fixing up the access permissions so I could read/write/delete them allowed the un-install and install to work just fine.
