Hi Ben,
Yes I did try
http://www.microsoft.com/en-gb/download ... aspx?id=35 in the very beginning but a little voice in my head suggested I try it again which is what I did and BINGO. Buy that man a pint, even better two pints
Having spent most of the week on this I decided to have one more go. So I searched the net for an answer to "c0000006" and found pages of stuff but no real solution except that this error code is caused by not registering the product (FSX). But if I cannot get a full install how can I register? So I downloaded the DirectX updates file and installed it, restarted my pc and uninstalled FSX, restarted the pc and reinstalled FSX. It worked! I've been doing this all flipping week but obviously doing something wrong. Anyway FSX installed and registered and Acceleration installed and registered and it is all working.
Same with P3D "0xffffff7" is their version of non registration - I think, from the forum. So, again uninstall, restart and install, run as administrator and straight into registration.
Now all (?) I have to do is add all the scenery packages, add-on aircraft and bells and whistles - that should keep me going for a few weeks.
Thank you Ben for giving me the final kick to try one more time, I appreciate you're taking the time and trouble to help.
Thank you to everyone else for pitching in, this is what makes this hobby so great; there is always someone somewhere who has the expertise and experience to get us poor souls out of the mire.
ATB
