What Is the “Excel 12.0 Object Library”?

First, let’s decode the name:

Excel 12.0 = Microsoft Office Excel 2007.
Object Library = A file (usually EXCEL.EXE or MSO.DLL) that tells other programs what objects, methods, and properties Excel has.

When you write VBA code in another application (like Access, SolidWorks, or an AutoCAD script) to automate Excel—creating workbooks, writing data to cells, formatting ranges—you need to reference this library.

Scenario B: You must have version 12.0 (Legacy Support)

If your project absolutely requires the 12.0 reference (e.g., maintaining a legacy VB6 application on a dedicated server), you must install Microsoft Office 2007 on that machine.

Locate your Office 2007 installation media (Disc or ISO).
Perform a standard installation (or a custom installation ensuring Excel is selected).
Once installed, the library will be registered in the Global Assembly Cache (GAC) and available for reference.
