VCN-1, after you make sure to have read the manual:
1. Start the "Shade_GUI" program, by clicking on the desktop icon
2. Select 'Load Day 1 From Preset'
3. Select a preset and 'Open'
4. Select 'Clone Day 1' to apply the preset to each day of the FSX 10-day cycle
5. Close-out of the "Shade_GUI" program
6. Start the "Shade" program from the desktop icon, which will then start FSX for you
I hope this helps! And obviously this is the simplest, 'get in and go' routine. If you are happy with a preset that you have chosen, then all you need to do is start the "Shade" program to start FSX with the preset installed.
