hey I use https://github.com/lukesampson/scoop to manage most of my apps and DS4Windows too.
scoop creates a directory junction at %userprofile%\scoop\apps\ds4windows\current which points to the latest version installed.
HidHide correctly adds DS4Windows at the junction and it worked fine for 1 day through multiple reboots (just found HidHide yesterday 
).
Sadly now it stopped working.
Pointing to the real folder makes it work again but that would be annoying to update everytime DS4Windows gets updated through scoop.
I already reinstalled HidHide without success.
The task manager shows DS4Windows running at the same junction too.
HidHide hides controller from DS4Windows if it points to DS4Windows linked through a directory junction
You suffer from a documented issue, it will be fixed in the upcoming release, stay tuned
