I am developing a winform desktop application that uses the Microsoft.Office.Interop.Excel library for processing Excel files.
I have included this file in the References section of my program, but when I build it as an exe and send it to another user's computer, they are required to download a Microsoft driver in order to use the Excel integration features.
How can I include the dll when I build my program, so that my users don't need to download and install a separate driver?
Updated to add:
My users all have Microsoft Excel installed on their computers, so this is a different issue than the related question.
Here is the error message the user receives:
As i remember Microsoft.Office.Interop.Excel requires Microsoft Office to be installed on your target machine. I recommend you to use ExcelDataReader which allows you to work with Excel workbooks and does not require any additional drivers etc. Check it out!

I was wondering about the following Scenario:
I developed a C# application, that generates Excel reports based on the Microsoft.Office.Interop.Excel Assemblies and installed the application on a Windows 2003 Server without installed Excel, but I don't get it to work there.
So basicly: Do I Need Office on the machine, where I want to use the above named assemblies or might it be for other reasons?
Thanks in advance for all well meant answers.
Yes, you need to have Excel installed on your server. Also, there are special licensing requirements for this, so please see:

I'm working to create and read MS Excel file in asp.net web application.
I'm not sure that it requires to install Microsoft Excel on server or not.
I don't want to install any licensed product on the server like MS office etc.
Please let me know how i can implement this functionality without installing MS Excel on the server or it is necessary to install MS excel on server?
Thanks
It depends on what you're doing, but more than likely, all you need is the Microsoft Access Database Engine.
This download will install a set of components that facilitate the
transfer of data between existing Microsoft Office files such as
Microsoft Office Access 2010 (*.mdb and .accdb) files and Microsoft
Office Excel 2010 (.xls, *.xlsx, and *.xlsb) files to other data
sources such as Microsoft SQL Server. Connectivity to existing text
files is also supported. ODBC and OLEDB drivers are installed for
application developers to use in developing their applications with
connectivity to Office file formats.
Edit, in response to
I just want to read and write MS excel files but i don't want to install anything on the server.
You can try EPPlus, which seems to solve your problem; though I've never tried it.
EPPlus is a .net library that reads and writes Excel 2007/2010 files using the Open Office Xml format (xlsx).
No it isn't necessary to install a full version of Microsoft Office. You can just use ODBC or OLE to open the files, provided you just need to do simple operations like read rows in worksheets (as if they were tables).
Use http://www.connectionstrings.com/ to look up the various .NET ways of accessing Excel using ODBC and OLE.
Effectively you need to treat the .xls and .xslx files as if you were querying an SQL database.
I have writeen a software which some part's process is reading data from excel file. I have used linqtoexcel for this. But ı can't run this app on machine not installed office. And I don't want to install "http://www.microsoft.com/en-us/download/details.aspx?id=23734"(Access DataBaseEngine). I know , Probles is base on this. So My app will be working on xp machine which stand 24 hours.My apps will run once a day. I am not authorized for install software , only run . I want to embedd AccessDatabaseEngine dll's as referance on VS 2010. Thanks.
Unfortunately it's not possible to just include the AccessDatabaseEngine dll's on the server and have LinqToExcel work. The database engine has to be installed on the server.
All,
I created a C# console app in VS2010 (.NET4). that hits a database and sends out emails.
It works fine when I run it from VS but deploying the app to a remote server has me befuddled. All I need to do is install this app on (1) remote windows server.
Should be easy, right?
Looking at the publish settings, I don't see anything that will just build it locally without creating an installer (From a CD-Rom or DVD-ROM) and the other 2 options really don't apply either, at least by their descriptions.
So here is what I did so far:
The VS2010 publishing options that I am given are as follows:
Step #1 Picked option 3
Step #2 Place generated files on remote server
Step #3 Ran the setup installer
Step #4 Get this error
Question
Am I approaching this correctly?
If not, what do I need to do?
Thanks
Notice the error:
The application requires that assembly office Version 12.0.0.0 be installed in the Global Assembly Cache (GAC) first.
Refer to this answer and this MSDN question which contains the answer I have quoted below:
We solved it by going into the Applications Files dialog under the publish tab of the Project's properties and changing the office.dll assembly to Include. It had previously been set to prerequisite (auto). --Dave3182
It looks like your application is leveraging Microsoft Office (2003, I think) COM objects. This will require the same version of Office to be installed on your server.
If you are leveraging Office format files (.doc, .docx, .xls, .xlsx for example), you can look into 3rd party libraries that allow you to create the formatted files without Office installed. If you are just using Outlook to send the emails, you should re-implement the feature using the .NET libraries instead.
