eocode3

Dear all,

I am trying to install geocode3 to STATA 12 SE, but the following message appears.

ssc install geocode3
ssc install: "geocode3" not found at SSC, type -findit geocode3-
(To find all packages at SSC that start with g, type -ssc describe g-)
r(601);


I already installed both
> ssc install insheetjson > ssc install libjson
Any tips?
Many thanks,
Guillem
