Hi! I think she's not going to awnser so I'll try to explain you
You have to install Rainmeter to personalize your desktop with that, go to rainmeter.com/
You first have to unzip the file, right click and select unzip (you must install WinRar). Then you'll have a folder, just double click and it will be opened. Inside that folder, there are two folders and the preview. The folders are Arriba (Top) and Abajo (Bottom). When you have copy the folder you want to install, go to "Libraries>Rainmeter>Skins" and paste the folder. Now go to Rainmeter application and click in "Refresh all" button. It should appear in the skins list!
