title: How to install VSIX (visual studio extention) from local drive to a specific version of VS when multiple version of VS are installed?
body: <p>Rather simple thing that got me stumbled. I have a VSIX file I'd like to add to VS2012. I also have VS2010 run on the same box. After poking menus for a <code>Browse</code> button, I just run the file  by double clicking on it. It got installed but into VS2010. Is there a way to install it to VS2012? Is VSIX file VS version specific and I need to get VS2012 specific VSIX?</p>
