Thanks for all the replies. The PMDG 777 sim is running perfectly. I finally did what I was putting off doing, uninstalling and reinstalling FSX Acceleration and PMDG 777 again. Here's what I thought might be the problem. I had remnants of FSX and PMDG 777 left on my C:/ drive, all files and folders related to them were deleted. I uninstalled FSX and PMDG 777 from my E:/ drive, installed FSX as per instruction on one of the forum guides. I do not believe it was installed correctly, reinstalled PMDG 777 to my E:/ drive FSX folder. I then went back into my C:/ drive and renamed my fsx.CONFIG file,so FSX would load a new one, made the changes as per guide, reloaded the UlAutomation file, ran the Runtime installer for DirectX again, I'm using 9c version from the FSX program. I think a lot of problems with PMDG 777 can be blamed on DirectX9c, it needs fixing,IMO. I then detuned the graphics settings on FSX, which seemed to cure my CTD problem, part of which came from not having used Runtime installer brfore. The setting are close to the PMDG Intro guidelines , and I also turned all my traffic sliders to 0. Maybe with my new GTX 770 I can run max settings for most all of the graphics, but this is working great with my Nvidia GTX550TI.  I've got plenty of CPU, the i5 3570k which should run at 3.8ghz when the turbo mode kicks in, and 8gb of RAM. I have not used my overclock of 4.5ghz yet, as I've been two weeks fooling with everything to try PMDG 777 running and get to land my 777 in Dubai. What a relief, I was wondering if I'd ever get here.

Thanks for the reply, I fixed the problem with a bit of help from PMDG. Actually PMDG did give me three links to C++ run times, but the first link is to a DirectX run time installer, so PMDG  trying to fix my DirectX got me thinking. I'm using DirectX9, have read there are less problems with it then DirectX10.
 
I decided to research DirectX9, and it looked like a later version DirectX9c came out in 2010, which is later date then the last copy of MSFX Gold I installed  on my HD with DirectX on it. I downloaded DirectX9c, and installed, then downloaded again the DirectX run time installer, the first link of the four PMDG gave me, ran it's program and the problem is fixed. Did the newer version DirectX9c fix the problem, not sure, but I'd guess yes. But did the DirectX run time installer fix any problems with DirectX9c? No way of knowing, at least it did not do any harm.

Thanks for the reply, I did some searches for FSX Gold and read that the Acceleration Pack was on a third CD. I'd assumed that FSX Gold had two cd's like the basic FSX, do not know how I missed seeing the third cd, but some how I did. Once I install this cd I should be okay.
