If you have a recent version of the nVidia drivers, but are unable to find the nView Desktop manager, try accessing it via the control panel first.
nview_desktop_manager
Next, click the ENABLE button
nview_desktop_manager_2
Now when right clicking the desktop you can choose nView properties and pull up the nVidea control panel
nview_desktop_manager_3
Thanks to willhouse for helping me figured out this.
