Emily L 0 Report post Posted April 22, 2019 I got a new computer and cannot use my old activation code for version 11 on version 12. The -22 error says "wrong license number You have attempted to activate Nitro Pro with a serial number from another version...." I have tried the activation portal and contacting cleverbridge but neither resolved the issue. Thanks in Advance Share this post Link to post Share on other sites
AllainU 0 Report post Posted April 22, 2019 Hello @Emily L, Thank you for reaching out to us through our Community Forums! In order for me to further assist you with your concern, could you please send me a private message and provide the serial number of your Nitro Pro. This matters because our business installers are different from the online ones. Thank you very much in advance and I am looking forward to hearing back from you.

AllainU 0 Report post Posted April 23, 2019 Hello @Emily L, Thanks for this information. Upon checking our records, this serial number is for Nitro Pro 11 and kindly note you cannot activate Nitro Pro 12 using the same key. To further assist you, please be informed that '-22 Error Wrong License Number' means the serial number you are trying to activate is for a different version of Nitro Pro. Kindly follow these steps: 1. Uninstall Nitro Pro 12 from your computer then reboot the machine. 2. Download your Nitro Pro 11 from these link/s: x64-bit: http://install.nitropdf.com/professional_1108470/en/burn/nitro_pro11_ba_x64.msi x32-bit: http://install.nitropdf.com/professional_1108470/en/burn/nitro_pro11_ba_x86.msi If you are unsure if your machine is using 32 or 64-bit, please refer to this link: http://kb.gonitro.com/knowledgebase#/search/64/000001874 3. After installation, you can activate by opening Nitro Pro 11, clicking on the Help tab > About Nitro Pro > Activation and entering your serial number. Cheers!
