You can choose one of several methods to install Jomres into Joomla or Wordpress. You can download the installation files from this page and following the instructions in the manual, install that way, however the easiest way is to use the Install From Web features both of the CMSs offer. This is usually quicker and easier to do.
Note that your new installations will not look anything like the demos. The demos take a great deal of time to setup properly so we offer Quickstart downloads, which are copies of the demos. You can then use these Quickstarts to get your new site up and running quickly. To download those Quickstarts you will need a Download and Support license.
Here you can see installation videos for each of the two CMSs.

If you're absolutely determined to do it the hard(er) way, then download these files and follow the instructions in the manual :)
Jomres for Joomla
Requires an installation of Joomla 3.2 or above.
This is the component installer for Jomres. It can be installed from Joomla Extension Manager just like any other component. Jomres Core itself is free, and enables you to have a basic yet working booking system on your site for one property. If you want access to plugins, which greatly extend the functionality of the system, or you need to manage more properties, please consider purchasing a Zero, Silver or Silver+ license.
Jomres for Wordpress
Requires an installation of Wordpress 3.8 or above.
This is installed like any other Wordpress plugin through the WP Plugin Manager and is the recommended process by which you can install Jomres into Wordpress. All it does is include a copy of the web installer from the section above which is run when you activate the plugin. When you choose to start the web installer will download and upzip Jomres Core. Follow the onscreen instructions as they're simple to follow.
