Install AutoIt3 and Scite difficult

hi,

I have been using AutoIt3 and Scite or years. Each time I install the programs on a new computer it's is difficult for me to find the correct settings: the au3 properties and keyword files are in the folder but no color highlighting and no build/compiles possible. I am a just a non professional building my own little tools to save me keystrokes.

Can you help me please,

thanks

Peter
