Analytics is a free online magazine covering the wider world of optimisation and data analysis. 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 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. Office July 2016 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. Free download nitro pdf for mac. 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. 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 site.

To download and use OpenSolver: • (either Mac or Windows, selected automatically depending on the machine you are using to visit this page). You can also try out our experimental (also ) for access to non-linear solvers. • Right click the downloaded zip file, choose Properties, and click the “Unblock” button. If you don’t see this button, you can skip this step. (This step is a new requirement following a July 2016 update to Excel.) Close the Properties window.

• Extract the files to a convenient location. (All files and sub-folders, including OpenSolver.xlam, must stay together; please do not move any files or folders out of the unzipped OpenSolver folder.) OpenSolver on Windows may not work if installed to an unmapped directory such as server myfiles or one that contains unicode characters.

• Double click on OpenSolver.xlam. There may then be a small wait as Excel checks the digital signature on the OpenSolver code. • If asked in an Excel Security Notice, give Excel permissions to enable the OpenSolver macros. You can click Trust all from Publisher if you do not want to be shown the Excel Security Notice again. • The OpenSolver commands will then appear under Excel’s Data tab on Windows, or in the Menu Bar on a Mac. • If using Excel for Mac 2016, follow the instructions further down the page to set up the solvers 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.

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”. Alternatively, you can copy the files from the.zip into the Excel add-in directory.
