Question details

The user is experiencing an issue where the Excel Solver add-in executes without actually modifying the targeted decision-variable cells.

How to Fix Excel Solver Add-In Not Changing Cell Values

Product: Microsoft Excel
Device & OS: not provided
Scenario: Running a data model optimization or following a tutorial using the Solver add-in to calculate optimal outcomes.
Observed behavior: The Solver tool finishes running without returning any errors, but the decision-variable cells remain completely unchanged.

Before you start

Ensure that your worksheet is not protected and that the decision-variable cells are not locked, as worksheet protection will prevent the Solver add-in from modifying cell values.

Solution 1Recommended

Contact Third-Party Solver Add-in Support

Since Solver is typically provided as a third-party add-in, contacting their dedicated support team is the most effective way to resolve complex configuration or model execution errors.

The built-in Excel Solver relies on third-party components to function properly. When it stops changing cells despite following tutorials correctly, it is highly recommended to reach out directly to the add-in developers so their specialists can review your model setup.

Open My Add-ins

Launch Microsoft Excel, navigate to the 'Insert' tab on the top ribbon menu, and click on 'My Add-ins'.

Locate Solver Details

Scroll through your installed add-ins to find Solver, click the three-dot menu (Options) in the top right corner of the add-in card, and select 'Add-in details'.

Access the Support Link

In the side panel that opens, scroll down to the 'Details + Support' section and click the 'Support' link to directly contact the third-party add-in specialists.

Contact Third-Party Solver Add-in Support

Third-Party Support Scope: Standard Microsoft support forums focus on built-in Office features and may not provide expert troubleshooting for mathematical modeling errors inside third-party add-ins like Solver.

Solution 2

Verify Solver Constraints and Model Setup

Incorrectly configured constraints or decision variables can cause Solver to immediately halt because it cannot find a mathematically feasible solution.

WPS Spreadsheet Data Analysis

Use the Built-In Solver Tool in WPS Spreadsheet

WPS Spreadsheet offers a built-in, fully integrated Solver tool for complex data modeling and optimization, eliminating the need to rely on external third-party add-ins. You can seamlessly run your models and instantly see the updated decision-variable cells.

1. Open Your Data Model: Launch WPS Office and open your .xlsx spreadsheet containing the mathematical model.
2. Access the Solver Tool: Navigate to the 'Data' tab on the top ribbon and click on the 'Solver' icon.
3. Configure Your Parameters: Set your objective cell, choose to Maximize, Minimize, or target a specific Value, and select your changing variable cells.
4. Add Constraints and Solve: Click 'Add' to define your constraints, then click the 'Solve' button to run the calculation and update your spreadsheet.

Frequently Asked Questions

Why does Solver say it found a solution but the cells didn't change?

This usually happens if the initial values in your decision-variable cells already represent the optimal mathematical solution that satisfies all constraints, meaning no further changes are necessary.

How do I enable the Solver add-in if it's missing from the Data tab?

In Excel, go to File > Options > Add-ins. At the bottom of the window, ensure 'Excel Add-ins' is selected in the Manage dropdown and click 'Go'. Check the box for 'Solver Add-in' and click OK.

Does WPS Office support Goal Seek and Solver functions?

Yes, WPS Spreadsheet natively supports advanced data analysis tools, including Goal Seek and Solver, which can be found directly under the Data tab on the main ribbon.

What should I do if the Solver add-in repeatedly crashes my spreadsheet?

Try disabling and re-enabling the add-in via the Excel Add-ins menu. If the issue persists, ensure your Office suite is updated to the latest version, or reach out to the add-in developer's support via the My Add-ins details page.
