Good Afternoon to all Simmers,I have bought the gatwick Extreme software but am having a problem installing it.I am told to delete the previous copy which was the Extreme trial version, big blue box on the runway etc.Can somebody tell me how to achieve this please ????Regards to all,Happichap

Happichap, When you run the installer for the new version, there should be a window with some buttons. One of those buttons asks you if you want to remove this scenery from the scenery.cfg(or something like that). After you click yes, it should ask you if you want to remove the files also. Click yes and you should be all set.
