Access to C:\Program Files (x86)\... was denied.
In order for Persona to operate properly within your Windows environment, it needs Administrative privileges for All Users. Not allowing this will prevent Persona from accessing the C:\Program Files (x86)\ for saving graphics and not run appropriately with the BNC video board.
Close the Persona software, right click the shortcut icon on your Desktop and press [Properties] > [Compatibility] > [Change settings for all users] and check [Run this program as an administrator]. After setting, restart your Compix system.
