Could not load file or assembly 'Excel, Version=2.1.0.0, Culture=neutral, PublicKeyToken=93517dbe6a4012fa' or one of its dependencies. The system cannot find the file specified

Revision 6
Hi,

I am getting the above error. Please give me a solution.

What I have done so far,
1) Added Excel.dll and ICSharpCode.SharpZipLib.dll
2) Included namespaces using Excel and using ICSharpCode.SharpZipLib
3) On file upload button click,

protected void btnUpload_Click(object sender, EventArgs e)
   {
       string xFilePath = fuAlumniList.PostedFile.FileName;
       IExcelDataReader excelReader = null;
       FileStream stream = null;
   }

Eventhough I have only this much of code,while I try to upload an excel file I am getting the error,
"Could not load file or assembly 'Excel, Version=2.1.0.0, Culture=neutral, PublicKeyToken=93517dbe6a4012fa' or one of its dependencies. The system cannot find the file specified"


I am using Windows Server 2008 R2 (64-bit OS) and MS Office (32 bit)
