You cannot install the quickstart version through the extensions installer mate!
The quickstart has to be extracted on your own computer and uploaded via ftp to a web folder or using a virtual php machine on your local pc.
Than you call this url and follow the installation steps.
Check out in the web how do you install a quickstart!
If you need the template / module / plugin - well that can be installed via extensions manager - but always check that you don´t need to unzip the zip first (sometimes a zip contains multiple zips with different versions of a extension).
