EDB database link to Oracle

When using a database link in Postgres Plus AS 8.3 to an Oracle instance
I receive...

SQL> create database link ezdev connect to pguser identified by pguser

2 using oci '//devdb:1521/ezdev'

3 ;

Database Link created.

SQL> select * from ezorder(at)ezdev;

ERROR near line 1:

unable to load OCI library: Access is denied.

Im on windows the enterprisedb user is an Administrator. What am I
missing? Thanks
