For the past year or so we've focussed development efforts on to VistaPro rather than the old Vista. The interface for variable display and selection is much faster and easier and there are plenty of advanced options now for plotting different types of charts with analysis bands, custom varibales, selection filters, Model Viewer ll based model colouring based on results, Wind Rose, MacroFlo arrows.
This has been done with the intention of removing Vista so the only results viewer option you will have is VistaPro. In the VE 2015 release we'll advance this by making VistaPro the default results viewer for all installations and also there will be a reminder pop-up if you do click in Vista to suggest using VistaPro instead.
It is expected that later in 2015/early 2016 the Vista option will be removed.
If there are any problems with VistaPro or reasons you would still use Vista then please do flag this up to firstname.lastname@example.org or post on our user forum as soon as possible so we can consider these and resolve before making this decision.
