Unable to Install V12.10.1.487

I am currently running V12.6.1.298 on Win10 Pro.  This Nitro version has Add-on issues with my MS Office products - had to disable the add-ons.  I noticed the new Nitro version available yesterday and downloaded the installer.  However, after the installer began the process I received the message the Installation Wizard failed.  I have never in my thirteen years with Nitro Pro had this issue.

Any ideas what I need to do?

Hi @John_G,

Thank you for reaching out to us through our Community Forums!

I recommend to uninstall Nitro pro using the cleanup tool then install Nitro Pro using offline installer.

You can download the cleanup tool here: CleanUp Tool  
Refer to the link below about how to use the cleanup tool:

Using the Clean Up Tool to Remove Nitro Pro

If you encounter issues during uninstallation or installation, please try running the Microsoft tool that fixes problem with applications that won't uninstall or install.


Once Pro is completely uninstalled, proceed on installing Nitro Pro using the offline installer. 
Please refer to the link below:

32bit - http://install.nitropdf.com/professional_12101487/en/burn/nitro_pro12_ba_x86.msi
64bit - http://install.nitropdf.com/professional_12101487/en/burn/nitro_pro12_ba_x64.msi

If you are not sure which to pick, this link will help: 

I hope this helps. 

Kind regards,

Hello Reymund G.

Thank you for the quick response.

I followed your outlined procedure using the VBS cleanup tool, restarted, then installed Nitro Pro using the offline installer.  No errors on the install portion but Nitro would not launch.  Received an "Entry Point Not Found" window. A procedure in "BCGCBPRO2430u120.dll" could not be found

Uninstalled Nitro again except using Revo Uninstaller Pro wherein I removed leftover registry entries from V12.10.1.487 and V12.6.1.298.  Ran the offline installer again and Voila!  

V12.10.1.487 now runs perfectly after importing Settings registry keys from the prior install.  Happy to see the MS Office add-ins now working again in WIN 10 installation of Nitro.
