RaGhul, yes it can, just to be clear every version can be installed on top of the older one, it's the Last Session preset that might cause some trouble if the GUI was changed but that issue rarely happened. And for those who wonder about Windows nLitement over older version nLitement, a big no. Silvereyes, also a fact which people forget is that nLite isn't difficult from the programming standpoint once the basics are done, it's just about research and listening. Since we all research together it's not really just me, I would never find 99% of the issues people report on this forum and on my email. There is also a small alpha team which finds critical bugs before public release, they are a great help when it comes to critical bugs. As you said it's all about managing, coding is easy, once you learn it and don't change projects it's a boring side-task.
