In Visual Studio 2013 .vsixmanifest shortcut in extension folder not working

Hi,

We have an extension for Visual Studio 2010, recently we migrated it to Visual studio 2013 .

This extension will be installed by an msi installer and the VSIX content is placed under the product name in "Program Files" folder, Not under the Visual studio\extension folder or user extension folder, the installer will create a shortcut of the  extension.vsixmanifest file in Visual studio\extension folder. The extension was loaded in Visual studio 2010 but  it doesn't work for Visual studio 2013.

Is there any other way to implement this in VS2013 ? (Deploying extension in custom folder and make it detected by Visual Studio 2013)

Thanks,

:-)
