Hi Dafydd,
PD8 is now up and running, and registered, however I still got the same error message after following the instructions in Part C. I than ran MS Clean Up Install and that solved the problem so I could completely uninstall 7, reinstall and then was able to install PD8 as you directed.
With regards to your comments, no offence as I much preferred your help rather than trying to contact Tech Support direct. I am not only new to video editing, but forums in general as this is the first forum I have ever used, and as you can see, just a few times. The reason where I live I had no internet connection, or a dial up connection, or had to travel several miles, so didn't spend much time on the internet. Now I have a satellite connection on this my main computer.
Again my thanks.
