Unzip complains that there are many duplicate files
Wordpress does show an error message but ask if i am sure i want to do this and that’s it, it does not install the theme
Also in your instruction in the PDF file you described a file called fuji.zip which does not exist
The only zip file is Fuji_Installable.zip and trying to upload this file to WP theme upload result the above]
The WP I am trying to install on is a fresh out of the box WP from EC@ so it could not be the issue
