Glad you found the solution. The _unzip_first thing causes confusion for more people than just you, if that helps. We're looking into a more unified installer that we're hoping to debut later this year. If everything goes to plan, that installation package will be able to install all the additional modules and plugins all at once, and make it easier to pick and choose what you're looking to do.
Until then, it's a little more tedious with all the individual installations. Fortunately, the Joomla update manager can be used to update most of the additional modules and plugins after installation, making it easier to keep things up to date.
Should you need anything else, just let us know.
Thanks,
Alex
