Hi,
I have a problem with my solver. I try to run my model.mod + data.dat
with couenne.
</p>
<p>
Command line :
ampl : model 'C:\<path>\my_model.mod';
ampl : data 'C:\<path>\my_data.dat';
option solver 'C:\OS-2.0-<a class="missing wiki">VisualStudio?</a>\bin\couenne.exe';
(I got it from <a class="ext-link" href="http://www.coin-or.org/Couenne/"><span class="icon"> </span>http://www.coin-or.org/Couenne/</a>,
windows version, "An archive of COIN-OR executables for MS Windows,
including a MS Windows version of Couenne")
ampl : solve;
</p>
<p>
processus starts : i have "variables", then "constraints" and "problem
size before reformulation..." and CRASH. "exit code 3221225477".
</p>
<p>
My model run without problems with KNITRO (ampl input).
I try to fix this problem but i meet some difficulties.
</p>
<p>
Thank you very much.
</p>

I assume you have downloaded one of the binary versions of Couenne for
Windows. If so, do you remember which one among those in

<p>
Also, it would be useful to have the model and data file that originated
the crash, in order to replicate the problem.

Thanks,
