Hi Jason,
The Layout distribute options that are in 32bit Pro (from the Align Objects dialog) have now been added to MapInfo Pro 17.0.2.
They will be on the Layout's Alignment menu. There are actually 2 different ways to distribute; 1) distribute selected objects relative to each other, and 2) distribute selected objects relative to the current page.
Both of these will be available in 17.0.2 as commands that can be added to the QAT or the Layout mini-toolbar, but only the 1st way has been added to the Alignment menu.
