Hot Ecommerce Installation Question

How do I install the Hot Ecommerce template with all the extensions, virtuemart and a demo for an already existing joomla installation? I seem to only be getting the template but nothing else. Please advise.

You want to install hot_start , ..hot_start.zip is included in .zip you got form us, you need to get all files from it to your web root that start joomla installation as usual with only difference that you must click on "Install Sample Data" during installtion

But when I transfer the files to the directory where joomla is already installed on my website I get the message in the screenshot attached and it doesn't give me any options to install anything. What is the problem with this?

Here's the text:

"PLEASE REMEMBER TO COMPLETELY
REMOVE THE INSTALLATION DIRECTORY.
You will not be able to proceed beyond this point until the installation directory has been removed. This is a security feature of Joomla!.
Click here when the directory has been removed."

normal joomla installation , you need to delete /installation directory on install completion

But it does not give me the option to install anything. It only tells me to delete the install directory which does nothing for an install of what I purchased from you.

You must first delete ALL files from your old Joomla installation and then upload files for the HotStart installation.
