Vsix extension cannot be installed to 2012 Isolated Shell application.

Hi,

I do have a 2012 Isolated Shell Application and I want to write an extension for it, but I cannot get the vsix to install my extension. My ShellApplication is found by the installer, but it won't let me install it:

Could it have something to do with the previous error message, that the vsixmanifest format is not supported? On both my ShellApplication and the extension, I use the new PackageManifest 2.0.0 format:

<?xml version="1.0" encoding="utf-8"?>
<PackageManifest Version="2.0.0" xmlns="http://schemas.microsoft.com/developer/vsx-schema/2011" xmlns:d="http://schemas.microsoft.com/developer/vsx-schema-design/2011">

  </Assets>
</PackageManifest>

Can anyone tell me why the extension cannot be installed on my Shell Application?
