error istallation add on

'm trying to install Asset-Flinger-master add on. But it does not appear in the user preferences.
The procedure I’m using is:

  • download zip file.
  • save zip file in a folder.
  • open blender and open user preferences.
  • click on install from file,
  • click on zip file, asset flinger.

At this point the following message appears:
modules installed from folder where i have clic into C:\Users\a\AppData\ Roaming\ Blender Foundation \Blender\ 27.8 \scriptsThen I close and re-start Blender
But in user preferences I don’t see the folder Asset Flinger.
How to install it properly?
at the suggestion i have download this link indicated on this page github.com/BlenderAid/Asset-Flinger
(below the first image),

and i try this zip file but an error message say:
Source files in in the add on search path: C:\Users\a\AppData\ Roaming\ Blender Foundation \Blender\2.78\scripts\addons
now what thing i must to do?
