, you can join several .exe's into one .exe. Then you can distribute a single file. The main problem - you must write the tasks (=code) for doing something that you want (and be familiar with some kind of scripting). Try AutoIt (free), vTask (shareware, but really powerfull) or xStarter (shareware for all, but for Russian speaking people - free
By the way, tasks can be very complicated (it depends ONLY on your skill). In case you familiar with Russian - I can post one more nice prog for automation, which has some underground features (written by real cracker from my country).
P.S. maybe I misunderstand, but do you want to use Construct as automation script? Or as automation shell for end-user? What exactly you would like to automate (file operations, scores, inputs, patching...)?
