Depends on the version of Photoshop you have. You can update CS6 to read them or Lightroom 4.
Or you can get Adobe DNG converter for free, which converts the Fuji raw to DNG which can be opened in any Photoshop version.
You do need the latest update from adobe as it has the latest Fuji update file in it.
Silkypix is just horrible.( but it works.)
