I have bought Ccleaner pro + on my computer and I want to install it on my android phone.
I have the licence etc, but no activation code.
I can find no way on the phone to enter the licence. It continually tried to recover from google or buy a new subscription.
So what do I do
If you have a multi device CCleaner licence it can be used to Activate CCleaner Android.
The Activation Code is your multi-device Licence Key.
