I have used the Saitek Software with no problems for years and before that Thrustmaster programming software. I use it because it allows me to program many functions using the rotary dials and all the other buttons. I have not messed with the AH mapper to much because I can get everything I want from the Saitek software. That does not mean that someone else could not get the same or more from the AH Mapper. Many people have opinions regarding the above issue. I am just letting you know what has worked for me with very little problems.
First thing I did was go the Saitek website and downloaded the proper drivers for my operating system (XP). Then I downloaded the installation instructions and the Saitek program software.
Followed the directions, it is specific in the driver installation as to when to plug in the X45. After drivers were installed and I checked in Windows XP game controllers and saw that it was properly listed and working. I then installed the programming software. After that, load the Aces High Profile. I will send you two files, one is my Aces High Profile the other is a MS Word sheet that has picture of the X45 and boxes that show what is programmed for each button. I print that out and keep by my desk for reference. I also pencil in changes that I want to make then go into Saitek programming software and make the changes. I find the programming software fairly simple, they have manuals that show how to do it. Also, I have looked at others profile to figure how they did it.
After the installation you should have a little icon in your trey at the bottom windows. You have to select the Aces High Profile to make it active then go into Aces High.
In Aces High, you do have to map the joystick, throttle and rudder axis. You will see that I use CH Pro Pedals for rudder but you can setup the X45 to control rudders.
