The problem is that the Navigraph install is creating a sub-folder (inside the A3XX Navigraph folder).  If you'd like, after running the installer you can go to:   C:\Users\[Your User Name]\Documents\Aerosoft\General\A3XX Navigraph   and move the folders from the Navigraph Sub-Folder (created by the Navigraph installer) and move ALL the folders/files from   C:\Users\[Your User Name]\Documents\Aerosoft\General\A3XX Navigraph\Navigraph   to   C:\Us
