Good morning.
I wonder if I may direct to you an issue that is linked to you indirectly.
I'm using Counenne via OpenSolver.
Increasing a problem from:

• 3046 vars; 3046 int vars; 2006 bin; 2681 rows;
  to:
• 7013 vars; 7013 vars; 4511 bin; 7281 rows;
  I get the following error:
  Process exited abnormally with exit code -1073741571.
  I can't debug such an error.
  Could you please tell me something about?
  Best regards,
  MC

Good morning again.
I'd like to add that, after a change of the OpenSolver parameters, the solution is running well, after 862 seconds I'd say that result will come out.
Based on the following suggestion (from OpenSolver Feedback: http://opensolver.org/discussion/) I changed some formulas and it looks fine.
I'd say the ticket is closed.
Thanks a lot to the team, and sorry again.
MC

It is probably a very large summation, eg sum(A1:A9999). You could split this into several smaller sum’s. Other than that, the only option is to wait for us to re-write the formula parser, which is on the radar but is a big job. Sorry not to have a better response at this stage. Andrew
