If Brillians is installed at your VAMC, the CPRS Tools menu has a link for Brillians either as "Brillians (SupraVISTA)" or "SupraVista" or some variation of the above. The link can be on the Tools menu itself, or on a sub-menu. Your colleagues and Clinical Informatics/CAC staff can help, if you don't see the link.
Once you are running Brillians, please create a desktop link using the "Create Desktop Link" near the bottom of the "File" menu on Brillians' main form.
You can start Brillians using the desktop icon even if CPRS is down (look for a green icon showing doctor's bag with plus sign).
