Understanding CCleaner Pro License Usage

Before proceeding with the installation, it’s important to understand the licensing policy. CCleaner Pro is typically licensed for multiple devices, such as a single PC, multiple PCs, or even for family use, depending on your purchase.

Single License: Usually, a single license is valid for one device.
Multi-Device License: If you have purchased a license for multiple devices (e.g., for 2 or 3 computers), you can use the same key to install it on your second (or third) computer, as long as the total number of active installations does not exceed the limit set by your license.

If you're unsure about your license type, check the details on your CCleaner account or the email confirmation you received after purchase.
