Configuring Scite editor without EXE file

Hi

I have a copy of Scite that i use for coding in a few other languages and would like to add AutoIT to it, but it looks from the download section on this site that the only way to do so would be to run the provided executable file?

Is there anyway to configure Scite to do the syntax highlighting and auto-completion without running that executable file?

Thanks in advance

Adam
