Note that "C:\Program Data\Cakewalk/Shared Presets" is different from "C:\Users\USER\AppData\Roaming\Cakewalk\Shared Presets\"
Finding the data and getting it properly imported are obviously two distinctly different steps. The system is obviously generating those GUID-ish directory names, so simply copying from one system to another is a low-percentage step.
I didn't readily see a way to do direct export/import CS data, which seems odd considering there is an Import option for ACT in Prefs, but no Export. It seems this is intended to only come from vendors.
