SP2-0750: вам может потребоваться установить ORACLE_HOME

Я получаю следующее сообщение об ошибке, когда пишу sqlplus в командной строке

SP2-0750: You may need to set ORACLE_HOME to your Oracle software directory

Вот детали пути

Net Configuration Assistance тоже не работает. Он не запускается из Program Files и при прямом доступе выдает следующую ошибку
