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

Andrew Mason (Team OpenSolver) says: January 25, 2017 at 8:48 am 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
