Download the plugin ZIP from the FW Real Estate product page on fastw3b.com. It is a free download — there is nothing to buy and no account needed to get it.
In the WordPress admin go to Plugins → Add New → Upload Plugin, choose the ZIP, click Install Now, then Activate. A top-level FW Real Estate menu appears in the admin sidebar.

Your Client Section on fastw3b.com is a different place and holds a different file: the subscription pack, if you have one. Do not use that file for initial installation.
Activation is non-destructive and does exactly two things:
The free add-ons ship inside the plugin ZIP and are ready the moment activation completes. Nothing is copied anywhere and there is no per-add-on install step.
Activation does not create any pages. You create the pages yourself and place FW Real Estate blocks (or shortcodes) on them. The plugin then discovers those pages automatically. See Setting up the front-office pages for details.
Everything you own lives under wp-content/uploads/fwre/ — never inside the plugin folder. This matters because WordPress plugin updates delete the entire plugin directory and unpack the new version in its place. Anything left inside the plugin folder would be destroyed.
