Hello dear,

You don’t have to upload the zip file but you’ll have to first extract or open the zip file that you’ve received titled “Illusive.zip“.
Unzip and Extract this file first using Winzip/Winrar/7z or any zip extracting software.

Within the unzipped theme package, you will find a number of folders such as Demo Content, Instruction Files, etc. There is also 1 additional zipped folder within, titled “Illusive.zip“.

Important: DO NOT unzip this “Illusive.zip” folder! This particular .zip folder should remain zipped. This is your theme file. You have to upload it directly onto your wordpress.

We hope we’re able to make you understand.
Please let us know if you still needs any assistance.
Thanks
