After you receive licensing information in a license certificate email, you need to install the license server and host the licenses. This involves accessing a Micro Focus web site and downloading license files called .slip files as described here.
When the StarTeam Server starts, it checks for slips and stores information about them in memory. It does not recognize new slips until the next restart.
Once the slips have been placed in the \License folder and the StarTeam Server has been restarted, the User Manager in the Server Administration Tool can display information about the slips and an administrator can assign licenses from those slips to users.
