Winrar is a program that compresses files, I did not realise that Winrar is a Dutch program, but it's very easy. You go to this site:
http://www.winrar.nl/
Step 1:
-Then you click on the books (download) on the left, next to ''WinRAR 3.93 (32 bit) voor Windows (Nederlandse versie)'' or (64bit) if you are running a 64bit Operating System.
-When running the setup, click ''installeren'', it will install, than ignore the next screen and just click ''OK'', and finally you click ''gereed''.
-Than you will probably see the directory in which winrar is installed, just click it away.
Step 2:
-download the WinRAR file from the site I posted before.
-click on the file with right mouse and than unpack the file.
I hope this is clear for all you non-Dutchmen.
