G’day
I have two computers. Please tell me how I can install the program onto my second computer
If you currently have a licence that allows use on multiple devices (ie. CCleaner Pro Plus or CCleaner Premium) then simply install CCleaner on to the the extra machine and activate it using your licence key.
If you currently only have a single device licence then you will either need to upgrade to a multi-device licence (CC Pro+ or CC Premium) or buy another single device licence for the extra machine.
If you need an installer then the latest can always be found here: https://www.ccleaner.com/ccleaner/builds
