I have a recorruing issue between my Microsoft Flight Simulator 2004: A Century of Flight and my Windows Vista Home Premium 64-bit OS. In the program files of the flight simulator, I have selected the 'Aircraft' folder. I then click on the folder of the aircraft I am wishing to update. Then, I proceed into the 'Panel' folder. Previously I downloaded a new panel for this particular aircraft, and for it to display, I need to edit the configuration settings of the 'Panel' folder. This is usually done through notepad. Having made the needed changes, I must save and exit out of notepad. This was done with no issue on one of my old computers (which is now dead.) and is the proper procedure to update a cfg. file. However, with this Vista, after attempting to save I receive a message that says "Cannot create C:\Program Files (x86)\Microsoft Games\Flight Simulator9\Aircraft\Continental B737-700 Kittyhawk\panel\panel.cfg file. Make sure that the path and file name are correct." The directory is as correct as it could possibly be, and I don't know why an issue like this would appear. I've tried to save the settings on Wordpad and other programs, and they all do the same thing. What is wrong with my computer and why will it not let me save changes to my cfg. files on my flight simulator?
