Installing to new PC and serial # not working - tried your deactivate - did not work


Recommended Posts


on 2/11/2019 I purchased the Nitro Productivity Suite with the forever updates.  Order Reference # 16*******.  I am installing to a new PC and it says that my serial number is not valid.  I went through the searching for the SN on your site to deactivate it and it says it is not installed anywhere to select to deactivate from.... Apparently you don't have customer service and instead i have to submit an open on your forum?   That is pretty crappy user support.  I can't give you my serial number to fix this because the entire world could see it.  I need this working in the next 24 hours for a work document I need to convert by tomorrow.

To resolve this activation issue, please uninstall the existing Nitro PDF Pro on your computer then install the latest build of Nitro PDF Pro 12 which is

You can find Nitro PDF Pro installer from the link below and activate it with your current version 12 serial number.

After installing Nitro PDF Pro, you should be able to activate using your existing serial number.
