Thank you for selecting the free upgrade to Scotflight for FSX V3.13
You will need the installer keycode which came with your original Scotflight for FSX purchase to install this software.
When prompted by the installer, indicate which keycode you have, and enter that keycode when prompted. This will give you full access to the V3.13 features.
If you have the Scotflight RAF Collection, indicate that you have an RAF keycode, and also enter that keycode when prompted. The installer will then create an integrated installation including the RAF Collection.
Please contact us regarding lost keys or technical support relating to your purchase.
