XE and SQL Dev work properly.
Connecting under XE database user "system" (it doesn't matter, the result will be the same).
Trying to connect to "localhost-1521-xe" I get
Status : Failure -Test failed: ORA-00604: error occurred at recursive SQL level 1
ORA-12705: Cannot access NLS data files or invalid environment specified
Trying to connect to "local/bequeath" I get
Status : Failure -Test failed: C:\oraclexe\app\oracle\product\11.2.0\server\bin\ocijdbc11.dll: Can't load IA 32-bit .dll on a AMD 64-bit platform
