OpenSolver is updated whenever new features are added or bugs fixed. Please check out the blog page for release details. You can also use the built-in update checker to keep up-to-date with the latest release.
OpenSolver comes in two versions, a simpler “linear” version and an “advanced” (non-linear) version with support for more solvers, including non-linear solvers. Both versions are available for Mac and Windows. On Windows, OpenSolver should work with Excel 2007 and later; we test it on 32 and 64 bit Windows 7/10 in Excel 2010/2013/2016. (Older versions worked with Excel 2003, but we don’t test this any more.) On Mac OS X, it should work using Excel for Mac 2011 with any version of OS X newer than 10.7.
OpenSolver for Mac: OpenSolver currently has limited support for Excel 2016 for Mac. Version 2.8.3 of OpenSolver includes initial support for Excel 2016 for Mac, and supports model creation and modification, as well as solving with the CBC and Gurobi solvers. Make sure your version of Excel 2016 is at least 15.28 for this to work. Unfortunately, the late 2018 release of Excel 16.16.7 has broken OpenSolver; if you can help us debug this, please email us at email hidden; JavaScript is required. However, our user Alexander reported in April 2019 that “OpenSolver works for MacOS HighSierra with the latest Excel update 16.24, but if you upgrade your OS to Mojave it no longer works.” (Thanks, Alexander.)
Windows July 2016 Office Security Update Microsoft updated the security requirements for add-ins in July 2016. You now need to “Unblock” the .zip file before extracting the files; please see the instructions below and this help item.
Available Downloads
OpenSolver Linear: This is the simpler version that solves linear models using the COIN-OR CBC optimization engine, with the option of using Gurobi if you have a license. Most people use this version.
OpenSolver Advanced (Non-Linear): As well as the linear solvers, this version includes various non-linear solvers and support for solving models in the cloud using NEOS; more info is here. Much of this code is still new and experimental, and so may not work for you.
You can see all our downloads, including previous versions, on our Open Solver Source Forge site.
To download and use OpenSolver:
Signed Code: Note that as of October 2014, the OpenSolver code is signed by the publisher “The University of Auckland”. This makes the code more secure. However, Excel will occasionally need to check the digital signature by contacting servers online, which can take a few seconds.
Support our Solver Community: OpenSolver includes open source solvers developed by COIN-OR. Without these, OpenSolver would not exist. Please support our solver developers by donating to COIN-OR.
Make OpenSolver Installation Permanent: OpenSolver will be available until you quit Excel. If you wish, there are two ways you can make OpenSolver permanently available in Excel. Either, use OpenSolver… About OpenSolver…. and check “Load OpenSolver when Excel starts”, or you can copy the files from the .zip into the Excel add-in directory. This is typically:
Windows XP:
C:Documents and Settings'user name'Application DataMicrosoftAddins
Windows Vista and later (7, 8, 8.1):
C:Users'user name'AppDataRoamingMicrosoftAddins
Mac OSX:

Installing Solvers on Excel for Mac 2016
If you are running Excel 2016 on Mac, you need to install the solvers after unzipping OpenSolver. Inside the unzipped folder, go to
Solvers/osx you will find a file called “OpenSolver Solvers.pkg”. Open this file and click through the prompt to set up the solvers on your computer (you will need to enter the administrator password to do so). After this you will be able to use OpenSolver as normal.
Using Gurobi on Excel for Mac 2016
Because of the sandbox, Gurobi is unable to find its license file when we start it from OpenSolver. This can be fixed by copying the license file “gurobi.lic” (which usually is in your home folder) to the following folder:
~/Library/Containers/com.microsoft.Excel/Data
Alternatively, you can open a terminal and paste the following command to put the license file in the right place (if your license file is in a non-default location you will need to modify this command first): Arial font family download mac.
cp ~/gurobi.lic ~/Library/Containers/com.microsoft.Excel/Data
Why do we need an installer for Excel 2016 on Mac?
Office for Mac 2016 is sandboxed, meaning that it can only run executables that are located in a set of whitelisted directories on the computer. We need to place the Solvers directory into one of these whitelisted locations so that we can run the solver binaries for OpenSolver. This folder is write-protected and needs admin privilege to modify, so we provide the installer to streamline the setup process.
Mac Users Using Excel 2016 or Excel Online
Get the new Solver App for Excel 2016 and Excel Online this free Solver app works equally well in desktop Excel 2016 and Excel Online – and handles the smallest to the largest, most challenging optimization models. 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 [email protected].
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.
