Only the most updated Photoshop can take advantage of this higher quality brush.
Dynamic brushes (abr) take full advantages of the photoshop brush engine and the brush preset tool. NBK Design dynamic brushes are tested in Photoshop CS5 + and Photoshop CC. It’s important to note dynamic brushes won’t work well or not at all with Photoshop previous versions because some of the brush presets DO NOT EXIST. Brush Preset panel is a key element of dynamic brushes.
Photoshop Elements – NBK Design dynamic brushes are tested in PSE 13 and 14 and are capable to use the brush engine according to these versions. Previous version of PSE do not support such brushes because they lack presets that will make the brush work. It’s important to check each description to make sure which versions were tested.
