Every instrument sold by ramé-hart ships with backup media of all the original drivers and software that were installed on the PC that shipped with your instrument when it was new. If you lost your media, then order this item for a replacement media. Replacement CD or Thumb Drive with the same version of DROPimage that shipped with your instrument and the correct camera driver for your model are included. Serial number required. These files are too large to email. If you are interested in upgrading to the newest version of DROPimage, then you should order this item instead.
