bought a new laptop

I have the CCleaner professional and I bought a new laptop. How do I put it on my new laptop ?

Simply install CCleaner on the new laptop, then open CCleaner, go to Options>About>Upgrade to Pro and enter your licence key and name.

You can download the latest CCleaner installer here: https://www.piriform.com/ccleaner/builds

If you have mislaid your licence key then see this:
