Been dropped in at the deep end here, so I'm hoping that someone here=20 may have walked this path already... In theory, is it possible to just move the CCS compiler folder from its=20 old Win environment, to an appropriate place that MPLAB-X knows about?=20 Or will there be more to it than this? I've asked CCS tech support, but who knows when they'll get back to me!
