How to install manually vsix (2011) in Visual Studio 2012?

Question

I\'m trying to install a vsix add-in in VS2012. However it looks like this add-in is available only for VS2010.

Is there any way to install it manually or to force

VSIX is just a zip-archive. Unpack it, locate the file extension.vsixmanifest. This is an XML file, open it. Locate the section SupportedProducts. It should look like the following:

    
        
            Ultimate
            Premium
            Pro
        
    

Copy-paste the VisualStudio section and update the Version attribute on the pasted fragment to 11.0.

Pack the contents back into a zip-archive. Make sure the archive have the VSIX extension. You're done.
