Yes, but not only that: to use the menu item "/Variable/X-12-ARIMA analysis" the time-series data must be of a frequency that x12a can handle, namely quarterly or monthly. You can check this by opening the (supplied) Ramanathan data set data9-7, which is quarterly: if x12a is installed correctly that menu item should be active.
