Visual Haskell projects cannot be created

Hi there,
 
I was pleased to find a Visual Studio compatible version of Haskell (my company 
has just started using a Haskell based language and I need to learn the 
language). The install went smoothly but I could create neither a console 
Haskell project nor a Haskell library project - Visual Studio reported the 
cabals had not been installed.
 
Regards,
