Looking at your screenshot all the required files are definitely there and I verified this in the downloads as well. The Template - Standalone doesn't include a Installation folder because it installs through the templatedetails.xml file in the back end of Joomla. If you are using the Site Shapers then it will have the installation folders present as that is how the Joomla Install for packages work.
I think there may just be some confusion as to the proper way to install a Template vs a Site Shaper. Be sure to follow the tutorials here if you are unsure as we lay it out step by step for each process.http://www.shape5.com/joomla_tutorials.html
