Alex thought for a moment before responding, "I'm using version 5.2.0.0348, the full version with a serial key."

Rachel's eyes widened. "Wow, that's amazing! I can see why you're so proficient with it."

As they parted ways, Alex couldn't help but feel a sense of satisfaction. He had not only helped his colleague but also demonstrated the power and versatility of Daemon Tools Pro. The software had become an indispensable tool in his own workflow, and he was glad to have been able to share its benefits with Rachel.
