Typically, IObit Driver Booster Pro licenses are device-specific, meaning that a single license is usually valid for one computer only. However, IObit does offer multi-device licenses at a higher price, which allows users to install the software on several devices within a household or organization. It’s important to check the specific terms of the license you purchase, as different editions may have varying terms. Always refer to the official IObit website or contact their support for detailed information regarding licensing options.
