Retrieve license key when registered email is no longer active and password is forgotten

Hi. I recently bought a new PC. I have not been able to find my license key to CCleaner in the old hard drive in order to activate it on my new PC (I am admittedly not very computer literate). Unfortunately, my registered email with CCleaner is no longer active and I have forgotten the password (I never needed them until now). My subscription to CCleaner was just automatically renewed this month so I want to get full use out of it ASAP. How do I change my registered email address and password in order to access my license key? Any help would be greatly appreciated. Thanks.

Hi @rick_315

Something easy then, the first job is to get CCleaner on your new machine activated as Pro:

Is the old hard drive still in the old PC?
If so then just open CCleaner on that machine and go to Options>License key to read your key from there, Once you have it then just put it into the CCleaner on the new machine to register/activate it.
(You are OK for a short time using the same key on more machines than it’s valid for. That’s because people do get new machines and need to transfer their licence from old to new).

If the drive is no longer in your old PC then try opening it and go to “#:\Windows\Program files
(where # is the drive letter).


Copy the whole ‘CCleaner’ folder to “C:\Windows\Program” fies on the new computer (replacing the one that is already there).
Open CCleaner on the new machine and it should now be registered as Pro (And have all the same settings that it had on the old machine).

Give another shout if you are having problems with either of those methods.

See the next post for what to do about getting your registered email address changed.

This is a user forum. We do not have access to accounts/billing here.

You will need to contact support to get your registered email address changed, you should tell them both the old registered address and the you want it changing to.
However it may take some time, see the note below

You can raise a support ticket by using the form here: CCleaner Support Community
(Do not try to change the language of that form, it has a bug and becomes unresponsive if you do that. If it happens then close and reopen your browser and try the form again without changing the language).

NOTE - The automatic support queue works off email addresses.
If the email you use when sending your request to support is not showing as registered to a current valid licence then you will not be seen as someone who has (currently) paid for support.
As an apparent ‘non-payer request’ your request will be non-priority and it may be a very long time (month or more) before the computer even shows your request to a support person.

PS. Sending multiple requests will not help - in fact it will slow a response down because each time you send another they all get automatically collected together as ‘further information’ and sent to the back of the queue again.
