Hi there!
This is another german promotion.
It normally gives you the german version of the software but the registration key works with the english version downloaded from other sites.
The software is a top-notch one. I strongly recommend it.

You must first have your own account on that german site. You register here:
http://download.softwareload.de/start-rc/start/
But the registration is not that simple if you don''t understand german.
 
After registration you go here ( while being logged in )
http://download.softwareload.de/O-O-DiskImage-3-Pro-PC-Welt/6061...
Click on Vollversion kaufen.
 
On the next page you must tick T-Pay ( per Telekom Rechnung ) and fill in the Gutschein-Code : PCWeltSoftware09. Then Click on OK
 
The next page Reduzierter Preis 0,00 click on "Weiter" and you''ll arrive at your own page "My license keys" ( Meine Vollversionen ) where you can see the actual license key and the download links for the 32 and 64 Bit Windows versions zipped installer ( 21,7 MB ) AND the O&O Disk Image Start-CD (ISO) ( 308 MB ).

Don''t know about the O&O Disk Image Start-CD (ISO)... UPDATE
Here''s a comment saying how to have the Disk Image Start-CD(ISO)in English:
In response to the ISO you can get, the German version is also English. Just tested it on a VM. All you have to do is alter your keyboard and timezone. Job done!
When you boot the ISO it asks for language, keyboard and timezone. All languages and timezones are there but it defaults to +1hr GMT and a German keyboard. Just change to what you want and off you go.
...but don''t bother to download the zipped installer because is the german version.
Instead you can download it here:
http://www.brothersoft.com/oo-diskimage-professional-edition-dow...
Or on the O&O site ( you can choose the 32 or 64 Bit Windows version )
http://oo-software.com/home/en/download/archive/index.php?produc...
 
The last very important detail:
When installing be sure you enter the exact infos:
In the field Name: the declared email address
In the field Company: For Personal Use Only ( without the quotation marks )
In the field License#: your personal license key

If you have troubles in registration on the german site or grabbing the licence key, just take a look on the screenshots on the site I found it. They are very well explained.
