body: <p>I'm trying to Export an Excel file from a <strong>Windows Form</strong> (C#.NET), as the application is installed on server. For most of the clients it is working fine but some client machines are getting following error after clicking export button:</p>
  
  <blockquote>
    <p>Could not load file or assembly 'Microsoft.Office.Interop.Excel, Version=15.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c' or one of its dependencies.Access Denied</p>
  </blockquote>
  
  <p>Those client machines are having office 2013 and 2007 installed.
  In my PC I got office-365, and its working fine.</p>
