What Version do I have?

A first line of ToolTip (mouse-over) on the DriveSecurity icon in the Windows notification area displays the version number (for example, 3.0).

s_1_2

If ToolTip (mouse-over) doesn’t show version number then you have an older version (2.X and below) that displayed on the bottom right of the main dialog:
DS_old_Mouse_Over

DS_Old_version
