www.ioncube.com/loader_installation.php

Now
Download the latest version of the plugin and component from here
www.joomlagooglebase.com/download/index.php

Now install the Plugin and Component, as you would any other Joomla extension, by going to
extensions > Install/Uninstall

Browse for the zip file you downloaded and press "Upload and install"

Then repeat for the second file.

(It makes no difference in which order you add them in.).

And that's it!!!

Now to add the licence
Once you get it working perfectly with the demo, so it exports 10 items and Google Base accepts them, you then need to buy and generate a licence.

So go to
www.joomlagooglebase.com/virtuemart-hsbc...le-base-licence.html
Buy the licence or licences that you need.

Once that is done you can go to "My Licenses"
www.joomlagooglebase.com/my-licenses.html

And generate a licence for your domain name.
Now upload this into
root/plugins/system/

Don't modify it, just add the txt licence file as you downloaded it from this site. Now when you go to the Google Base component you installed it will say Registered in Green, if not check everything again thoroughly.
