How Do I Deactivate — and Re-Activate CCleaner Software?

To deactivate and re-activate CCleaner, first check whether your subscription uses an account-based license or activation key. Sign in to your CCleaner account and review the registered devices or subscription settings. If you are moving CCleaner to another computer, deactivate or remove the old device when the subscription allows it, then install the appropriate version on the new device.

Steps to Deactivate and Re-Activate CCleaner

Open CCleaner and access its account, subscription, or license section. Sign out or deactivate the current installation if that option is provided. Keep your purchase receipt and license information available before removing the software.

On the replacement computer, download CCleaner from its official source and complete installation. Sign in using the same account associated with your purchase, or enter the valid license information when prompted. Confirm that your subscription appears active and that the correct device is registered.

If re-activation fails, verify your internet connection, account credentials, license status, and device limit. An expired subscription or previously registered device can prevent activation.

FAQ: Can I use CCleaner on another computer after deactivating it? If your subscription permits device transfers, you can generally deactivate the old installation and activate the software on another eligible computer. Exact limits depend on your license terms. Avoid third-party activation tools, which may expose your account or device to unnecessary security risks.
