Users can obtain Solver immediately from Microsoft AppSource. Over 100,000 existing “cloud Solver” users will receive the new version automatically. When your model gets to big for the free add-in contact us about upgrading.
If you're still using Excel 2008 for Mac, you can download Solver for Excel 2008 here -- but we highly recommend an upgrade to Excel 2011, for many reasons including a better Solver!
Using the Excel 2011 Solver for Mac
Starting with Excel 2011 Service Pack 1 (Version 14.1.0), Solver is once again bundled with Microsoft Excel for Mac. You do not have to download and install Solver from this page -- simply ensure that you have the latest update of Excel 2011 (use Help - Check for Updates on the Excel menu).
To enable Solver, click ‘Tools’ then ‘Addins’. Within the Addin box, check ‘Solver.xlam’ then hit ‘OK’.
To use Solver, start Excel 2011 and create or open your workbook. When you're ready to use Solver, click the Solver button on the Data tab (the bundled version of Solver doesn't use the menu Tools Solver.) . The Solver Parameters dialog should appear, in the language of your Microsoft Excel 2011 installation. Click here for Solver Help, applicable to both Excel 2010 for Windows and Excel 2011 for Mac.
Use the Solver Parameters dialog to select your objective, decision variables, and Constraints. Then click the Solve button. Solver will seek the optimal solution to the problem. When it's finished, the Solver Results dialog will appear, and the final values of the decision variables will appear in your workbook in Excel. To pause or stop Solver while it's solving, press the ESC key, and click Stop (or Continue) when the Trial Solution dialog appears.
Caution: Don't make changes yourself in Excel or your workbook while Solver is solving. Changes in Excel while Solver is solving, will have unpredictable results, including crashes in Solver or Excel. See the FAQ about Solver as a Separate Application.)
If You Updated to Excel 2011 SP1 and Installed Solver from Solver.com
If you've previously updated to Excel 2011 Service Pack 1 and after doing this, you've also downloaded and installed the Solver package formerly available on this page, you'll be fine, but you can encounter a problem (involving which version of Solver gets loaded and used) which we can easily help you solve. Just email us at at firstname.lastname@example.org.
Read the FAQ to learn how Solver for Excel 2011 was developed, special considerations in using this Solver versus the one in Excel 2008, and what to expect in the future.
The History of the Excel 2011 Solver for Mac
Before Microsoft began bundling the Solver with Excel for Mac, Frontline Systems worked with Microsoft's Mac Business Unit to bring you a faster, easier to use, and more powerful Solver. The version that we provided was free and 100% compatible -- your existing Solver models would work without any changes, whether they're from Excel 2004 or 2008 for Mac, or Excel 2003, 2007 or 2010 for Windows.
Matches New Solver for Excel 2010 for Windows
Solver for Excel 2011 for Mac has the same new features and user interface as Solver for Excel 2010 for Windows -- which is greatly enhanced over Solver for Excel 2007.
Includes New Evolutionary Solving Method
Based on genetic algorithms, this method complements Solver's linear programming and nonlinear optimization methods. Use it to find solutions for models with IF and LOOKUP functions.
Global Optimization for Nonlinear Models
Automatically run the GRG Nonlinear Solver from multiple, intelligently chosen starting points, to find better solutions when the old Solver would be "trapped" in a local optimum.
New user interface matches Excel 2010
