Okay, I did a complete reinstall of FSX after being sure that it was completely removed from my system.  IN THIS ORDER-
1.  Installed FSX STANDARD to C:/FSX instead of using (x86) Program Files directory for my 64 bit system Running Win 7 - rebooted
2.  Activated FSX and loaded game to set settings.
3.  Rebooted
4.  Installed Acceleration, which comes with SP2 and activated.
5.  Rebooted
6.  Loaded Game to set settings.
7.  Rebooted
8.  Installed 737 and activated offline.
9.  Rebooted
10. Loaded Game and then the Aircraft 737.  Worked!
11. Shut game down and installed the 777 and activated.
12. Rebooted
13. Loaded FSX then 777.  Worked!

It's a complete fresh install and different location on my harddrive - no FSUIPC installed nor any of my other addons. But the two planes from Captain Sim are working beautifully!  Thank You, Captain Sim.
