No, Best Free Keylogger cannot be installed on a remote machine. You need to have access and administrative privileges to the computer in order to install Best Free Keylogger.
Technically, you may be able to install the program using a third party application like TeamViewer after gaining access to the machine, but that will be a violation of the Terms of Use and the End User License Agreement as well as certain laws in some jurisdictions if done without proper admin privileges and/or permission from the owner of the computer.
