title: Restrictions on installing extensions or add-ins in Visual Studio 2010 Express
body: <p>I installed MSVC++ 2010 Express and trying to figure which extensions (vsix) are available to install. There are some extensions in the <em>Extension Manager</em> (section <em>Online Gallery</em>). All of them from <a href="http://visualstudiogallery.msdn.microsoft.com/">Visual Studio Gallery</a>. To be sure I installed some <a href="http://visualstudiogallery.msdn.microsoft.com/9df9c61c-4d90-43e5-9aa1-a58786b7a1e4">extension</a>. It, therefore, cannot be said that the express editions of Visual Studio do not support installing Extensions or Add-Ins. At first I decided that <em>Visual Studio Gallery</em> is the place for allowed extensions. I downloaded from there <a href="http://visualstudiogallery.msdn.microsoft.com/67620d8c-93dd-4e57-aa86-c9404acbd7b3/">PowerConsole</a> extension and tried to install it. However, I got message box with following text:</p>
  
  <blockquote>
    <p>Visual Studio Extension Installer<br>
    This extension is not installable on any currently installed products.<br></p>
  </blockquote>
  
  <p>The question is, What are <em>exact</em> limitations for installing extensions in Visual Studio 2010 Express?</p>
