How to Fix When Loading Excel Solver Not Working
This tutorial demonstrates how to fix the error when Solver is not loading in Excel.
Solver is an add-in that is provided with Excel and is used to perform “what-if” analysis by providing alternative answers to a formula in a cell based on values you may pass to the formula from other cells in your workbook. To use Solver, first enable the add-in. On occasion, once the add-in has been enabled, it does not work. This tutorial discusses a few reasons why this may occur and how to fix the problem of Solver not working.
