The problem here is that you need to add write permissions for the vst3 folder:

> **[02\_Getting\_started\_windows](https://github.com/iPlug2/iPlug2/wiki/02_Getting_started_windows)**
>
> C++ Audio Plug-in Framework for desktop, mobile and web - iPlug2/iPlug2

I already added write permissions for the vst3 as in the wiki, do you have any other suggestions?
