Is it possible to output the used solving algorithm?
I'm usually working with Xpress Workbench or the optimizer via bash on Linux. Out of curiosity I compared its performances with the Xpress IVE 64bit and there I noticed the statistics tab with detail...
IVE is a very old product that is no longer being maintained. Therefore it did not keep up with recent changes in the optimizer and some of the information displayed may be off. Some of the information provided in the statistics display is not read from attributes but instead collected from callback invocations throughout the solve. The "Status: Unfinished" for the LP is a bit unexpected here but may result from a very easy model that is solved already in presolve (with 0 simplex iterations).
I suggest you don't focus too much on the output of IVE for your model but instead check the relevant attributes directly. For example, the way to check the solve and solution status these days is via attributes SOLVESTATUS and SOLSTATUS.
