From your Administrator panel Choose Extensions/Manage and just click this and it will give you the install window.
Make sure you have extracted all extension from the bundlesoft packag and drop them one at a time to install. Once each one is installed you will get a Success window telling you they were installed successfully.
For Joomla! 2.5 it is just a little different.
You will want to choose Extensions/Extension Manager.
You will want to browse and choose each of the files and Choose upload and install.
When it is finished you will get a Success Screen.
