Installation Defence on all Windows versions (about 106 MB):
1) You execute the link, either directly or by saving the file.
2) The downloaded program "bm-defence(.exe)" suggests to extract the contained files
to a folder "c:\games\qbtrain.dfs" ; you start this by clicking on the "unzip" button.
3) At the end of the extraction, an installation program starts.
It creates an icon at the desktop and entries in the Windows Start menu,
you may start the program using one of that.

When the download is finished, you execute the file by double clicking it.
3) The Mac standard installation runs, which you proceed by clicking on Ok or Continue.
The installation results in a new program (application)
and in a new icon in the Launchpad, Defence.
- If an older version of the program already was installed, please delete it
before the new installation by dragging it from the folder "Applications" to the trash.
- If during the installation a password is asked for, it is that of the Mac user.
The product key is needed only after the bridge program has started.
- The Mac standard programs often use up the first page of the Launchpad,
so you will find "Defence" on the second page.
- The new version (b) corresponds functionally to the browser version, but uses local files,
i.e. with the installation done, it does not need an internet connection.
