  1. Hi Admin,

    I was curious to about how to retrieve values of Lower Bound on objective function of MILP in OpenSolver? (This is required in case solver is not able to solve the problem in given time limit)

  2. I’m using Excel 2003. I downloaded OpenSolver 1.3beta.zip and opened OpenSolver.xlam. However, I received “compile error” message in OpenSolver Main(code) at “ribbonLoaded(ribbon As IRibbonUI)”.
    OpenSolver.xlam of OpenSolver 1.2beta version can be opened without error message but I couldn’t see OpenSolver in menu bar. I guess it is because OpenSolver 1.2beta is not supported for Excel 2003.
    Could you help me how to solve this problem?
    Thank you in advance.

    1. Yama, Thanks for your feedback. We have a version that fixes this Excel 2003 problem, and will be releaed soon. Andrew
