Unable to open Dynamics.dic forms and tables script using dexterity

Hi Guys,

I installed Microsoft Dynamics Great Plains 2016, in my machine. I also installed Dexterity from tools folder inside Microsoft Dynamics GP setup folder.  I opened Dynamics.dic file in Dexterity , but i am not able to view any script or tables. 

Please suggest me what to do to view the source scripts in Dexterity.

thanks
