My Microsoft Flight Simulator X keeps saying "You have not installed direct X 9" even though I have already installed it again and again FIVE TIMES!!!!
I looked in registry editor (regedit) and it says

I think Flight Simulator can't detect DirectX9
How can I get Direct X 9 detected?

Microsoft DirectX System Requirements

Some video card manufacturers have updated drivers that are specifically designed to work with DirectX 9.0. It's possible that these drivers will benefit performance, quality, or stability of games running DirectX 9.0. Please make sure you check with your video card manufacturer to see if such drivers exist for your video card.
While your existing drivers should be as compatible with DirectX 9.0 as they were with DirectX 8.1, you may need to update them to take full advantage of some of latest DirectX 9.0 enhancements.You may find current drivers either at Windows Update or on the Web site of the company that manufactured your hardware. Drivers available from Windows Update have been extensively tested and certified by Microsoft's Windows Hardware Quality Labs (WHQL.)

How to Determine the Version of DirectX Using the DirectX Diagnostic Tool

http://support.microsoft.com/kb/157730/EN-US/

To use the DirectX Diagnostic Tool to determine the version of DirectX that is installed on your computer, follow these steps: 1. Click Start, and then click Run.
2. Type dxdiag, and then click OK.
3. On the System tab, note the version of DirectX displayed on the DirectX Version line.
4. On the DirectX Files tab, check the version information for each DirectX file.
5. When you are finished checking file versions, click Exit.
If Windows cannot find the dxdiag program, DirectX version 5.0 or earlier is installed on your computer. If this is the case, download and install the current version of DirectX.

To download the latest version fo DirectX, visit the following Microsoft Web site:

Dxdiag says directX 9.0a is installed on my computer but Flight Simulator keeps saying "DirectX 9 is not installed on your computer.This program cannot run."
Is there a problem with the registry?

It is more likely it is a problem with the installation of the flight sim.

See if the following helps:

Have you tried the sim on another computer?

Have you tried using the DirectX tool to see if your Direct X is working properly?

What video adapter do you have?
Do you have a program named Expertool (installed as part of your video adapter or sound software)?

Have you tried the Games and Multimedia Troubleshooter in Windows help
(accessed by clicking start/help and typing troubleshooter in the box)

Is this sim made for XP or is it for a previous version?
