Hi Victor,<br><br>What version are you using? This seems to be fixed already in trunk. <br><br>The version number you updated is from an older versioning scheme. It would be nice to make it match the real CBC version number, but this is not actually a "number" and has hence been added to the solver name (see below). Do you happen to know if the version number you updated is necessary and if not, will replacing it with a zero suppress its use?<br>
