AllainU 0 Report post Posted October 22, 2019 Hello @HANADI NASRI, Thank you for reaching out to us through our Community Forums! Did your machine just installed any major Windows Updates? To further assist you with your concern, kindly note upon the upgrade of the operating system or installing a major Microsoft / Windows update, the Computer ID is changed, as it is comprised partially by the operating system. Once changed, this will no longer recognize the original installation causing the program to revert to trial mode. As a workaround, I just made an adjustment on your license, so you can now activate your copy of Nitro Pro by going to Help tab > About Nitro Pro > Activate, entering your serial number and clicking Activate. Then you can now activate your copy of Nitro Pro by going to Help tab > About Nitro Pro > Activate, entering your serial number and clicking Activate. Thanks for choosing Nitro Pro and I hope this helps! Share this post Link to post Share on other sites
