Install Enfold

I purchased Enfold but cannot install it.
I simply went into the WordPress “Plugins / Add New” to bring up the ” Install Plugins” dialogue. I went to “Upload” and navigated to the “Enfold” folder where the “Style.css” file was located (as per the WordPress instructions). I zipped the folder and uploaded it. It uploaded but did not install.

Any help would be truly appreciated. I would even pay your team to help install this theme.

Thank you in advance,
Timothy
