I tried to edit my cfg file in PMDG 747-400X program located at ms games/simobjects/airplanes/PMDG747-400X but when addin g to the file it asks me if I want to save the changes but then will not allow me to save the changes. I turned off UAC with no change in results. I logged on as administrator and extrracted terxture straight to PMDG folder but it showed up in 747-4008i. My question is does PMDG have some restriction in place to keep me from installing a delta texture in my 747-400X folder. If PMDG does not have a restriction on downloading textures that don't come from them can someone tell me how to install a delta texture to PMDG747-400X.....henry murray laurel delaware

You need to actually run Notepad with the Run as administrator command for this to work. UAC or your account being an admin account are not the same thing - the Run as administrator command runs the process using the highest level "Adminstrator" account, which is hidden by default.Things like this are the reason we recommend installing FSX outside of the default Program Files or Program Files (x86) locations - this is Windows's "protections" causing this.
