Could you make a tool to run at post-install to make the installed one become lite? (preferably with optional features). This could be easier for you to make it compatible with future versions.
Thanks in advance.
PS: A GUI based one would be nice but there's no need to use GUI if your Batch Script's syntax-and-use is embedded on itself. I suggest to use a switch (for example "-?") to request the documentation, like DOS commands do.
PS2: This is not my native language… please excuse my bad english.
