RobynG83 0 Report post Posted January 18, 2018 I checked the article about how to locate the serial number for Nitro Pro and followed the instructions by going to Help > About Nitro Pro. My serial number ends with XXXXXX. Are those X's the actual serial number? Or does it not give away the last digits of the serial number for security reasons?

Alex E. 0 Report post Posted January 19, 2018 Hi @RobynG83, The X's appear when the serial has been masked. This is usually the case when using a company serial. I recommend contacting the person who purchased the serial if you require access to it. Share this post Link to post Share on other sites
