title: Installing VSIX to Visual Studio 11.0 and 12.0 using WIX
body: <p>I'm trying to install VSIX to two versions of Visual Studio and it is possible when doing it manually:</p>
  
  <p><img src="https://i.stack.imgur.com/BnWVg.png" alt="enter image description here"></p>
  
  <p>But when I'm trying to install the package using MSI installer generated by Wix 3.6 the vsix is installed to VS2012 only.</p>
  
  <pre><code>&lt;Component Id="VSPackageComponent" Guid="E54DBAAF-4961-492C-AA8A-FFE3C4C77BA3"&gt;
        &lt;VSExtension:VsixPackage File="VsPackageInstaller"
                                 PackageId="8cc311e8-5f48-4816-b1ee-6c873fe0dc71"
                                 Vital="yes" Permanent="no" /&gt;
        &lt;File Id="VsPackageInstaller" Name="VSProject2012.vsix"
                                      Source="VSProject2012.vsix"/&gt;
  &lt;/Component&gt;
  </code></pre>
  
  <p>And this package is not uninstalled during msi uninstall (it worked for some time before). GUIDs are identical (PackageId and Identity Id in manifest).</p>
  
  <p>Should I use these <a href="http://blogs.msdn.com/b/visualstudio/archive/2010/06/09/vsix-best-practices.aspx" rel="nofollow noreferrer">recommendations</a>?
  Or should I use WIX 3.7?</p>
