Hi there, I am looking for some advice if possible. I am trying to add a new aircraft to Flight Sim X (well a repaint of the default 737 actually). Now the readme file tells me to copy the texture folder to the 737 aircraft folder in fsx which I do with no problems but then it tells me to copy and paste a paragraph of text from the dowloaded file to my aircraft.cfg file. It tells me where to insert the text and I do that as instructed but when I come to save it I have a message saying access to Microsoft Flight Simulator X aircraft config file was denied.
What do I have to do in order to be able to save the file after I have made the adjustments?
