Sir you can install any of the 264 scripts (which includes The Hosting Tool) on your site. Just login to the Enduser Panel of Softaculous and search for the script you want to install and install it on your domain.
You may refer to the following guide on how to install a script:
http://softaculous.com/docs/Install_a_Script
If you do not find a script that you wish to install you can suggest the script we will review it and will add it if possible.
