HOW DO I INSTALL THE DESKTOP CLOCKS ANS ADD-ONS!?!?!??!

Which clock?

You need a program, regardless of which one. There is usually a link to information about and download of the program required right above the various libraries.

Well, assuming you are referring to onw of the many clocks available in the DesktopX Objects library, you will need DesktopX http://www.desktopx.net. If not, then you'll need to just follow goodmorphing's suggestion that you use the program link at the top of the library page you downloaded the clock from to see which program you need for your specific clock.

Good Luck!

thank you i needed DesktopX

Horayyyyyyyyyyyyy!
