The installer needs to write files to the system area and hence requires administrator privileges.
Some third-party anti-virus programs could interfere with the installation process by preventing the installer from correctly accessing the system area. If you do encounter programs, try restarting your system with any third-party virus/security programs disabled.
We design our software to be used by real people: researchers, teachers and students - on their own machines. We do not recommend complex IT installations such as "Windows Roaming Profiles". In our experience, these cause unnecessary complexity and seem incongruous in the modern "laptop age". IT personnel wishing to persist with roaming profiles should do so at their own risk; we provide some advice on the use of roaming profiles.
