Have downloaded and installed AutoIt as well as ScITE and can run scripts with no issue in ScITE.
Have also installed VSC (Visual Studio Code) and have installed Damien's extension for AutoIT.
When trying to do various operations in VSC, I see:
F5 = command 'extension.runScript' not found
CTRL+F5 = command 'extension.check' not found
CTRL+F6 = command 'extension.launchInfo' not found
ALT+M = command 'extension.LaunchKoda' not found
Thanks!
