ClickProject and then click References. The Referencesdialog box appears. Scroll down the list until you find Microsoft Excel object library, and then select the item to add a reference to Excel. If the correct object library for your version of Excel does not appear in the list, make sure that you have your version of Excel properly installed.

You're not going to find it. It's not downloadable from MS (or anywhere else, at least not legally).As has been mentioned, the "best" thing to do is develop with the lowest version you need to support. But many times, this isn't always possible or practicle for any number of reasons.Theoretically, you *can* develop your app using early-binding and a later version (such as you using the Excel 10 object library) and it will run just fine with an older version of Excel. The object libraries for all versions of Excel are binary compatible (meaning the GUIDs for objects are the same). However, you must be VERY, VERY careful that you don't use features found in later versions of Excel that don't exist in the earlier versions. For example, the object library for Excel 10 might have objects, properties, or methods that don't exist in the object library for Excel 9. If you use any of those, your app's not going to run with that older version of Excel (you'll always get some kind of runtime error). This is why it's recommended you use the lowest version you need to support because that eliminates any chance of using a feature found only in a later version.Bottom line is that if you develop with a later version of Excel and your app needs to work with an earlier version of Excel, YOU have to be absolutely 100% sure you're not using objects, properties, methods, etc. found only in the later version. Practically speaking, that's not necessarily so easy to do. The best thing you can ultimately do is have your program thoroughly tested by users having an older version of Excel if you can't do so yourself (and it's always best to have others do testing anyway because they're always going to find bugs that you won't).-- MikeMicrosoft MVP Visual BasicP.S.By any chance, did you also ask about this in general.discussion under the name Vanny? I'm just asking because it's remarkably similar. If so, don't do that in the future. Multiposting using the identical subject and name is bad enough, but when you use a different subject and post under a different name, it's 10000x worse.
Your reference needs to be reachable and one of those file types. But what if it's not? In my case, I pointed the File.Open dialog to c:\program files\microsoft office\office14\excel.exe and I got an error:
The beauty of VBA is we can reference other Microsoft objects like PowerPoint, Word, and Outlook. We can create beautiful presentations. We can work with Microsoft word documents. Finally, we can send the emails as well. Yes, you heard it right. We can send emails from Excel. It sounds awkward but, at the same time, puts a smile on our faces as well. This article will show you how to work with Microsoft Outlook objects from excel using VBA codingVBA CodingVBA code refers to a set of instructions written by the user in the Visual Basic Applications programming language on a Visual Basic Editor (VBE) to perform a specific task.read more. Read on.
The library is called early binding by setting the reference to the object. We need to set the reference to the object library because without setting the object library as MICROSOFT OUTLOOK 14.0 OBJECT LIBRARY. We cannot access the IntelliSense list of VBA properties and methods. It makes writing code difficult because you need to be sure of what you are writing in terms of technique and spelling.
Excel Object DescriptionApplicationTop Level Object, used to access workbooks in excel.WorkbookAn excel file consisting of several spreadsheets. Used to access a collection of Worksheets or the active sheetWorksheetThis is an excel spreadsheet. Here is where we populate the spreadsheet through the Range objectRangeA cell or set of cells. This object lets us populate a cell, a row, or a column. Any aspect of a cell, including color, can be changed through this object Table 1 - Core Excel Objects
Clicking ok produces an assembly that serves as a wrapper around Excel's automation calls. Now we are ready to use Excel in our GridView. The first step is to construct an Excel application object. Construction an excel application object will launch the excel application process. The construction behaves like a CreateObject in Visual Basic.

It gets this information by referencing the object's type library. When you go to Tools > References... and check the box next to "Microsoft Excel 16.0 Object Library," that is what you are doing. You are telling VBA, "Hey, whenever you need to resolve one of these Excel.Application method calls, go fetch the offsets from this here object type library."
Remember, with early binding, the offsets were resolved at compile time based on the object library on our development machine. And within that Excel object library, the Quit method was 4 columns over and 5 rows down. But on our end user's computer, that address offset now holds the Range property!
With late binding, the method offset gets resolved at runtime. Instead of relying on a type library on the development computer, we get the method offset directly from the COM object itself on the end user's computer. 2ff7e9595c
