Demo Installation Package - Extracting the .zip file from Quickstart gives error

I want to Install the "quickstart" package into an existing Joomla
In your information you write:

1. Download your purchased theme and unzip the file to your pc
2. Extract the .zip file from Quickstart folder >> I tried it on 2 templates (Barber & Onepage)
and both gives the same error message.


Do you have an instruction for me how to make an onepage website with the Barber template
without using the quickstart package?

Thank you in Advance!

You dont have to extract the file manually.
[hr]
Just upload the _{quickstart.zip} or _{quickstart.jpa} and the _{kickstart.php} file to your server and then point your URL > www.yourdomain.com/kickstart.php
After that follow the instructions on the screen
