title: How can I fix the Microsoft Visual Studio error: "package did not load correctly"?
body: <p>I installed Visual&nbsp;Studio&nbsp;2012 and <a href="http://www.devexpress.com/Home/Mission.xml" rel="noreferrer">DevExpress</a> 13.1. As Visual Studio started, it generated an error shown by this attached image,</p>
  
  <blockquote>
    <p>The 'Microsoft.VisualStudio.Editor.Implementation.EditorPackage' package did not load correctly.</p>
    
    <p>The problem may have been caused by a configuration change or by the installation of another extension. You can get more information by examining the file 'C:\Users\must\AppData\Roaming\Microsoft\VisualStudio\11.0\ActivityLog.xml'.</p>
    
    <p>Continue to show this error message?</p>
