CCLeaner is breaking a software registration

[doctor atomic]

Hello,

I'm using this French dictionary software : Grand Robert : https://www.lerobert.com/dictionnaires/francais/langue/dictionnaire-le-grand-robert-de-la-langue-francaise-abonnement-annuel-3133099010289.html

They issue a license key that I can use 3 times.

Each time I run a CCLeaner clean operation, it somehow removes the registration information Le Robert is using. I need to register again, and I'm stuck after three registrations ...

I asked their support staff, they say they don't know, and I should ask CCLeaner support.

What could happen ? Is there a way I could debug that, or get more info to pinpoint where the problem is and how I could add an exception to CCLeaner?

Thanks

I don't know for sure but it sounds as if they are keeping that information in a cookie. (*unless you are running the Registry Cleaner)

Are you using Health Check or Custom Clean?

If it is a cookie then Health Check will always remove it, anytime/everytime that you run Health Check.

Custom Clean can keep cookies so that they do not get deleted.

You need to identify the cookies from that website, and in Options>Cookies move them to the 'Cookies to Keep' side.

See 'Option 2' in this article, the article is a bit old but the option still works like that:
https://www.ccleaner.com/docs/ccleaner/ccleaner-settings/choosing-which-cookies-to-keep

Custom Clean will then leave them alone. (But Health Check will still delete them if it is run).

To set Custom Clean as the default screen that CCleaner opens with got to Options>Settings and change 'CCleaner Home Screen'

* If you are running the Registry cleaner then don't do that.
It is not needed and is not recommended except as a technicians tool to help fix a broken computer.
Running a registry cleaner when not needed can stop your computer working properly.
