If I understand you correctly, you want to install some executable programs in you own space on your your school system.
You can not do that and there is no way to pass this access denied unless the system administrator agrees and loose the resource access right. This the way of all Unix/Linux systems and metwork system do. Otherwise, the systems can be too easy to be damaged. The exceptional ones are your own PC or LANs at home, where youself is the default administrator, who has all the access rights and power to control over everything on your systesms.
