Purchased and downloaded Gemini template, rocket launcher, and gantry5 (see file list below). Gantry installed fine and so did the template but not rocket launcher. I get the following error when I attempt to install rocket launcher. I'm using the latest Joomla version 3.7.1. Anyone know what's wrong?
Warning
JInstaller: :Install: Can't find Joomla XML setup file.
The Joomla package cannot be installed through the Extension Manager. Please use the Joomla! Update component to update Joomla.
That is the expected behavior, the RocketLauncher includes a full Joomla installation, Gantry, the template, extensions and demo data and can therefor only be installed as a NEW Joomla installation and NOT be installed into an already existing site.
