-22:error -wring license number

[Eamonn 0]

Hello,

I have changed to a newer laptop.

I have deactivated NitroPro (pre-2012 version; 2 activations on earlier laptops) using the licensing portal.

When I proceed to activate using my license number, I get the error message "you have attempted to activate Nitro Pro with a serial number from another version...".

Any help would be great.

Thanks

Eamonn

Hello @Eamonn,

Thank you for your message.

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. Looks like we need to uninstall the current version of Nitro Pro on your computer and install Nitro Pro 6. We then activate it using your serial number. Kindly follow these steps:
 
1. Uninstall Nitro Pro from your computer by going to Control Panel > Programs > Programs and Features then reboot the machine.

2. Please clear all your downloads folder or delete all downloaded Nitro installers. This step is important because we noticed that if you are saving all the installers and you download them in the same folder (like the downloads folder), the EXE can pick up any MSI installer in that folder and you may pick-up one of the older builds instead of the newly downloaded package.

3. Download your Nitro Pro 6 using these offline link/s:

x32-bit: http://install.nitropdf.com/professional/archive/62306/nitro_pdf_professional6_ocr.exe 
x64-bit: http://install.nitropdf.com/professional/archive/62306/nitro_pdf_professional6_ocr_x64.exe

If you are unsure if your machine is using 32 or 64-bit, please refer to this link: https://kb.gonitro.com/knowledgebase/#/search/64/000003790 

4. After installation, you can activate by opening Nitro Pro, clicking on the Help tab > About Nitro Pro > Activation and entering your serial number.

Thank you for choosing Nitro and I hope this helps!
