I just downloaded a VSIX file from the Visual Studio Gallery.

How do I install it in Visual Studio?

VSIX is a Visual Studio extension installer. You must have Visual Studio 2010 or newer in order to install them, but you should be able to install it by double-clicking the .vsix file. Alternatively you should be able to install it from within the VS Extension Manager (Tools->Extension Manger)

See more about VSIX files at Quan To's Visual Studio Extensibility blog

How to install Visual Studio Extensions

To summarise, there are three options:

  1. Install via Extension Manager (Tools/Options)
  2. Install via Visual Studio Gallery.com (download and open directly or save then double-click)
  3. Install via "xcopy" into %appdata%\Local\Microsoft\VisualStudio\10.0\Extensions

The above answers didn't help me; I couldn't install it through the extension manager and there was not default application for .vsix. However, I needed to open it (right click > Open with...) with Microsoft Visual Studio Version Selector and it worked.

I think you just reload Visual Studio after downloading the VSIX. During the launch Visual Studio looks for the VSIX file and incorporates all the required changes.

Which version are you referring to? As heavyd pointed out VSIX is only relevant in VS2010 –  Diago Jan 14 '10 at 21:42
Visual Studio only looks if you put it in the right place! –  Benjol Apr 22 '10 at 6:44
