Rainmeter will run on Windows 7 (Service Pack 1 and Platform Update required) and above. The same installer may be used on either 32-bit or 64-bit systems, and all skins and features are compatible with both architectures.
Rainmeter is not available for non-Windows systems, including Mac OS and Linux, and there are no plans to support these operating systems.
Start by downloading the Rainmeter installer from Rainmeter.net.
To install Rainmeter, run the installer program that you downloaded, and follow the instructions. (See Installing Rainmeter if you need more detailed instructions, including steps for installing Rainmeter as a portable application.)
Rainmeter will run automatically after it has been installed.
