For those who care...
We used Windows Remote Assistance via Live Messenger to finally fix this.
I deleted all the files from the temp folder, and started the Steam install from a command prompt using the command line option "SteamInstall /?"
LOL, I was trying to see what the command line options were. But after that the install stopped at 26% as it was doing, then restarted and seemed to work fine.
So Tensa, is it all good now?
