Most campus license software that can be freely used by students and staff of the Science faculty, can be found in the
install network share.
You can find the contents of the install share via http from the campus.
Another way is to connect the install share in windows using cifs, the link is:
Consult this page on how to connect to a network share.
It is often possible to install this software directly from the install share. Often a license key is needed, it can be requested by mail to postmaster. Every software package has its own license requirements. Sometimes it can only be used on university owned computers, sometimes it can even be used by students at home.
