How to extract ".rar" file
First of all, you need to download "Winrar.exe" from this page, which locates
in "Other" Program category. Then setup the program.
All games here are in ".rar" file,
for example:
plant vs. zombie.rar
To extract this .rar file, Right-Click on the file, then choose extract here
then you will get a new file or folder.
after that you can setup the game freely.
thanks
