Sophos Anti-Virus 10 - Will not install - Unexpected product state 1 for product

I have a Windows 2003 Server that will not install Sophos Antivirus - 9 or 10 Client. It was running a successful Enterprise Console but it wouldnt install Sophos AV manually or by push from the console.

I have looked in these forums and a intensive google search and only found one reference to Unexpected product state 1 for product with code {034759DA-E21A-4795-BFB3-C66D17FAD183} but it had no solution.

I have removed everything off the Server including Enterprise console and have used an Sophos Removal Cleanup Utility. Now if I try to install either the Sophos Anti Virus 9 or 10 Client (Just to get some protection on) it immediatelty throws up the above error. Below is whats in the log file.
