Dear all,

I'am working on an optimization problem using C++ and encountered the 

 ERROR: CPLEX Error  1217: No solution exists.

So I decided to export the lp model and parameters and use the interactive optimizer to analyse the problem.  But the interactive optimizer finds a solution without any problems

So my question is:

Why does the outcome vary, even though parameters and model are equal (I diasabled heuristic callbacks)

Thank you very much in advance!

Edit: I'am using version 12.5 and i dont have the opportunity to update it.

Please try exporting a SAV file instead of an LP file and try again with the interactive.  With that, you should get the exact same results.
