How to install updates

Hallo together!
I´m a new member at this Forum!
I´ve got a mail, that there is an update für my Plugin (WP1 slider).
Ok I have done the download.
Now I have to cancel the old Version of this Plugin in my word-press-Installation, before I can install the new one??? In this case, I cannot overwrite the old one, am I right?

thanks for your answer
