A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data
I have no idea what "options" you're referring to but there is no download required. The Analysis ToolPak [as well as Solver] is included but does need to be activated. The installation is simple. Go go Tools> Excel Add-ins in the main menu (or click the Analysis Tools tool on the Data tab of the Ribbon or the Excel Add-Ins tool on the Developer tab) then check the box & click OK.
You may need to restart Excel but the Analysis ToolPak functions will then be available from both Tools> Data Analysis as well as by way of the Data Analysis tool on the Data tab of the Ribbon.
