Hi Dutch,
Well I have had partial success in as much as it is now installed on the hard drive. I Created exceptions in the Avira software, and in Malwarebytes, I re ran DX9Redist as you suggested,.
I tried a quick combat, and it went through all the set up process and came to the loading screen, sounds from the airfield were heard and then the 'CFS3 has stopped working'error message, followed by the shut down message, so I am back where I was when we first started talking.
I have gone round in circles trying to stay logged into this buggy forum to post this btw!!
