The launch mode has options of 32-bit and 64-bit, at the launch mode selection the available functionality will be highlighted by the icon, for example, in 64-bit mode some connections (highlighted in the window) may not be available.
If the Remember choice is selected, the subsequent S#.Designer launches will feature the preset settings.
