Simply download and install the Free version. The simplest way to download the Free installer is from here: https://www.ccleaner.com/ccleaner/builds

Once installed open it and go to Options>About>Upgrade to Pro.
Enter you registered name and key as asked then click on register.
(The name/key will be shown in the one you already have installed in Options>About>License Information).

There's more on registering, and what to do if you have problems here: https://support.piriform.com/hc/en-us/articles/204043844-How-to-register-and-activate-CCleaner-Professional#if-you-get-an-error-saying-that-your-license-key-is-not-valid--0-9

If you only have a licence for one machine you should uninstall CCleaner Pro from the old one. (You can then put CCleaner Free on that machine).
