Hi, first of all you need to download and install Rainmeter from www.rainmeter.net/. Once running, just double klick on a rmskin package to install the downloaded skin. If no skin will be activated during installation, simply klick on the Rainmeter Task Icon to open the management interface. Here you should see a list of available skins on your system. Select skins you would like to show here and activate with double klick or load button.
