If you update your contact or payment details, you need to tell them as soon as possible. What happens if I change my contact details or bank details? These are the three main reasons why Windows 10 might block your attempt to install CCleaner.

CCleaner accepts VISA, Mastercard, Discover Card, American Express and PayPal.
