dale white Posted July 11, 2020 Report Share Posted July 11, 2020 I am trying to get the price to upgrade from Version 6 of Nitro PDF Professional to the current version. On the upgrade screen, I enter my serial number from the CD sleeve ( box purchased at a local retail store). I get the error message "We were unable to validate your serial number". The number on the sleeve is the following format: 2346XX-XXXXXX-XXXXXX. I recently deactivated my copy of Nitro on an old computer and uninstalled it. I re-installed and activated it on a new computer. The re-installation had no problems. Help is appreciated. Link to comment Share on other sites More sharing options...

dale white Posted July 15, 2020 Author Report Share Posted July 15, 2020 Thanks Reymund! That was the answer I was needing. I will try the trial version first to evaluate if I want to upgrade. Can I install the trial version while leaving my current version installed? Thanks for the help. Link to comment Share on other sites More sharing options...
Official Nitronaut Reymund G. Posted July 20, 2020 Official Nitronaut Report Share Posted July 20, 2020 Hi @dale white, You can only have 1 Nitro Pro installation on a machine. You can uninstall your current Nitro Pro then install the latest version of Nitro Pro in trial. After trial period, you can uninstall then re-install your current version of Nitro Pro then activate it. Kind regards, Link to comment Share on other sites More sharing options...
dale white Posted July 23, 2020 Author Report Share Posted July 23, 2020 Hello Reymund, I deactivated my Nitro Pro version 6, then uninstalled it. Then I downloaded and installed version 13. It opens up and says the Trial has expired. I have repeated this process 3 times, same result. What am I doing wrong? Also, my old Nitro Pro disk is version 6.0.0.29. However, when I had trouble with Nitro a few years back, I was given a link for installing an updated version 6. That link was for a 32-bit version which does not work on my newer 64-bit computer. Is there a link for the 64-bit version so I don't have to reinstall from disk? Thanks again! Link to comment Share on other sites More sharing options...
Official Nitronaut Reymund G. Posted July 25, 2020 Official Nitronaut Report Share Posted July 25, 2020 Hi @dale white, Here's are the direct links of Nitro Pro 6 installers: 32bit - http://install.nitropdf.com/professional/archive/62306/nitro_pdf_professional6_ocr.exe 64bit - http://install.nitropdf.com/professional/archive/62306/nitro_pdf_professional6_ocr_x64.exe The Nitro Pro 13 shows a trial expired since there is an existing Nitro Pro that was activated on the machine. If your Nitro Pro 13 is still installed on the computer and would like to test it under trial, please send me it computer ID. The Nitro computer ID can be found under Help tab > About Nitro Pro > Activate/Deactivate > Advanced. Please copy the Computer ID and send it to my via private message.
