Check the Solver Add-In box and press OK. Have questions or feedback about Office VBA or this documentation? Please see Office VBA support and feedback for guidance about the ways you can receive support and provide feedback.On Windows, Solver may be added in by going to File (in Excel 2007 it's the top left Windows button) > Options > Add-ins, and under the Manage drop-down choosing Excel Add-ins and pressing the Go button. This example loads the previously calculated Solver model stored on Sheet1, changes one of the constraints, and then solves the model again. If False or omitted, the current model specifications and options are erased (equivalent to a call to the SolverReset function) before the new specifications are loaded.
If True, the variable cell selections and constraints from the LoadArea are merged with the currently defined variables and constraints. A logical value corresponding to either the Merge button or the Replace button in the dialog box that appears after you select the LoadArea reference and click OK. For example, SolverLoad("Sheet2!A1:A3") loads a model from Sheet2 even if it is not the active sheet. The range represented by the argument LoadArea can be on any worksheet, but you must specify the worksheet if it is not the active sheet. The last cell optionally contains an array of Solver option values. The first cell in the LoadArea contains a formula for the Set Target Cell box in the Solver Parameters dialog box the second cell contains a formula for the By Changing Cells box subsequent cells contain constraints in the form of logical formulas. A reference on the active worksheet to a range of cells from which you want to load a complete problem specification. If Solver does not appear under Available References, click Browse, and then open Solver.xlam in the \Program Files\Microsoft Office\Office14\Library\SOLVER subfolder. In the Visual Basic Editor, with a module active, click References on the Tools menu, and then select Solver under Available References. After the Solver add-in is installed, you must establish a reference to the Solver add-in. For information about how to do that, see Using the Solver VBA Functions. Before you can use this function, you must have the Solver add-in enabled and installed. Note The Solver add-in is not enabled by default. Loads existing Solver model parameters that have been saved to the worksheet.
