After downloading the latest bits of the Office 2007 RTM ISO’s it was time to install it. 
There are no changes in the installation as I can see at first sight from the latest beta, everything worked fine and smooth and was without much interaction, just the serial key and some optional customization and then about 10 minutes of waiting and I was up and running.
Before installing make sure that you remove all betas and updates to them including any add-ins such as the Save as PDF or XPS , otherwise the setup will exit.
When you are done you can go to the Offce site to find the updated add-ins such as the Save as PDF or XPS.
