Cant Re-install

[Raper]

I installed a css server and tried to install mani admin plugin. Since it didnt work i thought it would help to reinstall it. So i deleted it all and removed the program. I then downloaded the hldsupdatetool but when i try to install it says the 'half life dedicated server tool is already installed on this machine' pic:
