Cause: Excel 2011 does not include the Analysis ToolPak. Solution: Download StatPlus:mac LE for free from AnalystSoft, and then use StatPlus:mac LE with Excel 2011. That last link used to include loads of comments from disgruntled Office for Mac users, but Microsoft seems to have removed comment functionality from that help center article. Enable Solver in the 'Add-ins' section of your Excel preferences if necessary. Open a spreadsheet with data you want to analyze. Click Data, then click Solver. Select a cell to use from the 'Set Objective' field. Check the 'Value Of' box, then enter a desired value. Solver Tutorial: Excel 2011 (Mac) Summary: This tutorial will show how you can activate Solver and the Analysis ToolPa k in Excel 2011 for Mac. Note, Solver was added back into Excel 2011 with. Service Pack 1. The Analysis Tool Pack is not included in the Mac version and needs a separate program as a work-around. Step 1: Open Excel 2011.

Below are answers to Frequently Asked Questions about Solver for Excel 2011 for Mac.
How is Solver for Excel 2011 different from Solver for Excel 2008?
IMPORTANT: 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 site -- simply ensure that you have the latest update of Excel 2011 (use Help - Check for Updates on the Excel menu).
Solver is substantially improved in Excel 2011, compared to Solver for Excel 2008. Its new features include an Evolutionary Solver, based on genetic algorithms, new multistart methods for global optimization using the GRG Nonlinear Solver, a new type of constraint called 'alldifferent,' and new reports. Its performance is greatly improved, especially on linear problems with integer constraints.
Solver for Excel 2011 for Mac matches the functionality and user interface of Solver for Excel 2010 for Windows. Excel workbooks containing Solver models and VBA macros controlling Solver can be created in Windows and used on the Mac, and vice versa.
How does this new Solver work with Excel 2011?
Solver's user interface is now written in VBA. Solver uses Apple's new Scripting Bridge technology to 'talk to' Excel when you are solving a problem. The Solver computational engine runs as a separate application outside Excel, rather than as an add-in inside Excel.
Who do I contact if I need technical support for Solver?
You can contact Frontline Systems at [email protected], or by phone at 775-831-0300 during normal business hours, Pacific time (GMT-7). Since this Solver is a free download, please understand that we're here to help, but our commercial (paying) customers come first.
What about my Solver models created in Excel 2008 or earlier -- will they work?
Yes, they should work without any changes. If you open a workbook with a Solver model that you created in Excel 2008 or Excel 2004, your model should automatically appear in the Solver Parameters dialog -- you can just click Solve.
I need to use Solver in a course, or with a textbook that uses Solver -- will I be OK?
Yes -- you can open course or textbook example Excel workbooks containing Solver models and use them as-is, whether they were created in Excel 2003 or 2004, Excel 2007 or 2008, or Excel 2010 or 2011.
Only the newest editions of certain textbooks include screen shots of the Solver dialogs as seen in Excel 2010 and Excel 2011. But if your textbook has screen shots of the older Solver dialogs, you should be able to relate them to the new dialogs fairly easily.
What is Premium Solver for Education? Is it available for Excel 2011?
Premium Solver for Education is a compatible upgrade for the standard Excel Solver for Windows that has been bundled with more than 35 textbooks, often used in MBA programs. It is not available for the Mac, but you can use Solver for Excel 2011 for Mac to open and solve models in workbooks created with Premium Solver for Education.
Does Frontline Systems offer any other software products for the Macintosh?
We've been working throughout 2009-2010 to bring you new and more powerful products for optimization and simulation on the Mac. If you'd like to know more, contact us or watch Solver.com for some near-term exciting news!
Of course, you can use Frontline's software for Windows on your Mac if you have Parallels, VMWare Fusion, or a dual-boot setup and you have Windows installed (XP, Vista and Win7 are all fine).
Solver as a Separate Application
If Solver uses VBA, why does it run as a separate application?
VBA is back in Excel 2011, and Solver uses VBA for its user interface -- the Solver Parameters dialog, Solver Options dialog, Solver Results and other dialogs. But the C API not available in Excel 2011. So the Solver computational engine (which is written in C++) runs as a separate application.
How does the Solver engine talk to Excel, if it runs as a separate application?
Solver uses Apple's new Scripting Bridge technology to 'talk to' Excel. Excel 2011 exposes an object model through Scripting Bridge, that Solver can access. Scripting Bridge is generally faster than AppleScript. But since it crosses process boundaries, it cannot be as fast as a computational add-in running inside the Excel process.
What are the consequences of Solver running as a separate application?
The most important consequence is that it's possible -- but certainly not advisable -- to make changes in Excel or your workbook while the Solver engine is solving your problem. Because Solver is trying to talk to Excel at the same time, the results will be unpredictable -- including crashes in Solver or Excel.
Excel Solver Add In
The important message is: Don't make changes yourself in Excel or your workbook while Solver is solving.

Incline Village, NV (PRWEB)November 16, 2010
Frontline Systems Inc., developer of the Solver in Microsoft Excel, is shipping new Mac OSX and Excel 2011 compatible versions of Premium Solver Platform and five plug-in, large-scale Solver Engines, designed to bring unmatched ease, speed, and power to solving challenging mathematical optimization problems with up to millions of decision variables. The new products are released as Version 10.5, in line with their counterparts on Windows. Free trial versions are available for download from http://www.solver.com/macsolver.
“We’ve brought the benefit of 20 years of optimization software development to the Macintosh,” said Daniel Fylstra, Frontline Systems’ president. “Mac users can now take advantage of the latest and most powerful Solvers available on any platform.”
Premium Solver Platform Upward Compatible from Excel 2011 Solver
Premium Solver Platform V10.0 for Mac is upward compatible from the new Solver for Excel 2011, and all previous versions of Solver for Mac and Windows – but it’s far more powerful. Its LP/Quadratic Solver handles linear programming problems up to 40 times larger than the standard Solver, and problems of virtually unlimited size – millions of decision variables – with plug-in large-scale Solver Engines. While speed is highly problem-dependent, it usually solves linear mixed-integer problems 10 to 100 times faster than the standard Solver, and quadratic programming problems up to 10 times larger at high speed.
PSI Technology Aids Users and Solver Engines
Premium Solver Platform includes Frontline’s Polymorphic Spreadsheet Interpreter (PSI Technology), refined over the past 10 years, which replaces the core formula interpreter used in Excel with an advanced interpreter that can analyze Excel formulas for properties (such as linearity and convexity) important for optimization, provide diagnostic aids to users, and automatically compute function gradients – critical for optimization – using algorithmic differentiation. The PSI Interpreter has a major impact on nonlinear problems, which can be solved up to 10 to 100 times faster than the standard Excel Solver.
Familiar Solver User Interface Enhanced
Premium Solver Platform features a new Solver Parameters dialog that looks familiar to users of the standard Excel Solver, but offers easier ways to create and modify the elements of Solver models. In place of a simple list of constraints, it displays an outlined list of all the elements of the model – objective, decision variables, and general, bound, integer, semi-continuous, and conic constraints. The last two constraint types go beyond the standard Solver, offering new power to users. Premium Solver Platform also includes a SOCP Barrier Solver that solves conic optimization problems.
New Object-Oriented API for Excel VBA Users
Premium Solver Platform supports the traditional VBA macros used to control the standard Excel Solver, such as SolverOK, and SolverSolve. But it also offers a new object-oriented API that provides direct high-level access to optimization models, and is compatible with the API used in Solver Platform SDK, Frontline’s leading tool for optimization and simulation in a programming language. This API, offered for the past four years in Frontline’s products for Windows, has proven very popular with users.
Plug-in Solver Engines Extend the Power of Premium Solver Platform
Frontline has ported five plug-in, large-scale Solver Engines to the Mac, that “plug in” seamlessly into Premium Solver Platform and extend its power. They include:
