Here is a list of things that don't work in the Demo version: Please note, the following features are not included in the Free Demo: • Extensive Systems Programming (ADI, HSI, EICAS displays inop) • Flight Management System (CDU inop) • Realistic Flight Model (flight controls locked in the Demo) • Custom system sounds and crew voice messages • Authentic Sound Set - PW and RR engines (alias to default 737 sounds in the Demo) • Collins WXR-2100 Weather Radar • Aeronautical Data including Terminal Procedures • Repaint Kit The one I highlighted explains why they did not work. ;) EDIT. I will uninstall it from my FSX, and install it in FSX-SE to see if it installs properly.

I didn't noticed that. Sorry, my fault. :-?
Very kind of you. Thanks for your help, appreciated, mate. :)
