In order to access ViCoS one has to connect to the Internet and go to the LEXUS webpage. There you can log in using the username and password that you use for your LEXUS account. In LEXUS main menu there is a button that redirects you to the ViCoS workspace. At the moment the browser supported by the Technical Department of MPI for the use of ViCoS is Mozilla Firefox - therefore we advice to use its newest version. If you do not have Mozilla Firefox, you can download it for free from www.mozilla.com. Moreover you will need to have a Java script activated in your browser. Finally, you will need an Abode Flash Player. If any of these applications is missing, your browser will notify you about that and suggest the appropriate download/installation.
