How many computers can I install CCleaner Professional on?

You can normally install CCleaner Professional on one computer (with some exceptions). If you uninstall the software, you can also install it again on another computer.

We create licenses for our Professional and Business products (per computer) with some exceptions. For example, if you buy a boxed copy of CCleaner Professional in a retail store, you may be able to install it on more than one computer. Please check the box or packaging for more details.
