We here now meet many customers all over the world,who are neglectful to lose the CD with software.So they searched on the internet for the software,as they think if they got the software ,then they can use their quantum resonance magnetic analyzer.But today we want to say the fact is not that.As when you get the quantum magnetic resonance analyzer,you'll also get one corresponding key-lock(also called encryption key) to protect the software.That means,only the one key-lock can open the specific software,others not.So dear customers who have lost the software,if you want to download the software,you need to let us confirm which version is your quantum analyzer.Thanks!
