Need Component Help

Hey, in order to use a program I have, I must Uninstall the API components by using the Macromedia Extension Manager. Only thing is, I have the extension manager, but I don’t see any option to do as this says. Pretty much I have to do everything on this page, Here.
EDIT: Oh and I found out how to install the new components, just can’t figure out how to get rid of others. If I really must.
