~ I was talking (ofcourse if have internet) for the possibility updating throught internet with a light-simple-small setup-exe (produced by inno-setup). But again is not a single self running portable file...
Your questions as i understand:
1) You wanna have a totally-stand-alone exe file. With just one file... (that will also exract openjava, .net if need, and the project) me too
...
2) New Updates smaller exe files... wanna check if openjava extracted... .net installed... and if all "framework" ok then run ?
I think will be great creating a project like that... may be need a third language or utility to do that... but sure will be nice !
answering...
1) The first is possible with the first setup (inno will do the job... i think)
2) ...need to think
