Why does visualizer only have one available license?

Visualizer only has one avaiable license, this makes it very hard for multiple users to use MS. Is this typical?

Users of MS_visualizer: (Total of 1 license issued; Total of 1 license in use)

Users of MS_visualizer: (Total of 1 license issued; Total of 1 license in use)

"MS_visualizer" v2015.060, vendor: msi
