Create a new folder on your desktop, run the exe and point it to the newly created folder. Once that is done, copy the contents of the new folder to the FSX\Captain_Sim\navigation folder and answer yes if asked to overwrite anything. You might want to backup everything in there, just in case. I did it this way. See:



I know the above image says that it is from the CS 767-300, but it uses the same navigation info as the 757.

Hope this helps.
