Run (1) is definitely using CBC.<br><br>And the exception message explains the issue. Core range constraints are not supported. I actually don't recall exactly why they are not supported and I can probably fix that. But, for the time being, just split up your range constraints into two constraints (<= and >=) and it should work fine.<br>
<br>"COIN Exception [ Range constraints are not yet supported. Please break up your range constraints into two constraints. ] at ..\..\..\..\src\DecompAlgo.cpp:L1170 in DecompAlgo::masterMatrixAddArtCols"<br><br>
I added a ticket to remind me to fix that: <a href="https://projects.coin-or.org/Dip/ticket/61">https://projects.coin-or.org/Dip/ticket/61</a><br><br>Run (2) looks fine, although it is using CLP and CBC.<br><br>Send me your MSVS project (and solution) file and see if I can figure it out. Unfortunately, I don't have access to a windows cplex license - so I am not sure how to test this.<br>

Turn up the log levels and post the log (or just send it to me directly).<br>
