Starting with Excel already open, go to the tools menu (up at the top of your screen), then select Excel Add-Ins. Next, in the Add-Ins box, select the Solver Add-In and click OK. If the Solver Add-in isn’t listed, then click browse and search there. Also, if you get a box saying that Solver isn’t installed yet, go ahead and install it. If you’re still having issues, feel free to use the TA lab and one of us will help you there as well.
