Istallation failure of minimserver on windows7

[Yasser]

I have two pc s containing music, l am having difficultu finishing installation of minimserver because of a problem with Winrar which I don't understand. On one PC installation is perfect and no problem, on the other pc after executing the file the final shortcut appears in a winrar window and the icon never appears in the function tray to start reading my music. I installed winrar again but still the smae problem exists.
