Greetings @Janaki Raman

Thank you for reaching out through our Community Forums!

An activation issue will likely occur if the version of the license does not match the version of the application that you would like to activate. 

Please check the version of your serial number using our license portal (link below):
https://licenses.gonitro.com/prd/portal 

From the license portal, kindly take note of the version (the Nitro PDF Pro application installed on the computer must match this version).

To check which version is installed on the computer, launch Nitro PDF Pro and then navigate to the Help tab > About Nitro Pro. 
If the version does not match the license's version, please uninstall and install the appropriate Nitro PDF Pro version. 

The Nitro PDF Pro installer (versions 13 and 14) can be located from the link below:
https://www.gonitro.com/product-details/downloads - please download the version that matches your serial number. 

If version 12, please refer to the link below:
32bit - http://install.nitropdf.com/professional_12169574/en/retail/nitro_pro12_ba_x86.msi 
64bit - http://install.nitropdf.com/professional_12169574/en/retail/nitro_pro12_ba_x64.msi

Kind regards,
