Where can i get the latest odbc providers from SQL Server 2012/2016?

I see some posts on line to an ftp site out there but I am unsuccessful at getting access to it. I have a version loaded on my server but get errors when querying cache'.

"[Cache ODBC][State : 22005][Native Code 22005]"

Any help would be appreciated.

the one we have might be version 2014.01.05851 64 bit (would that make sense?)
