First of all, NSIS ended up screwing over my computer to such an extent that whenever I pressed "A" windows deselected the currently active window... I have no idea why, or how, but it reappeared after I installed NSIS and compiled something. I installed NSIS on my laptop without any problems whatsoever, so I might try my hand at it again, but it's not likely in the near future (at least not until I've finished working on the following feature I'm about to mention).
HTA, or HTML Application, is basically a web page run in Internet Explorer's local page viewer. As some might know, web pages can run Visual Basic Script directly (or at least at times, or in a Windows environment). The thing is: I can use this to make a GUI for CarE, providing more options and combining the vanilla and EFLC versions in a more elegant way.
Don't expect these changes to happen soon, though; this is just to let those who actually follow this mod know that CarE isn't, strictly speaking, dead yet.
Having GUI on CarE would be actually pretty cool. Should you make it, I'll be looking forward to it.
