nitro pro 12 not loading

[lloydmajor]

My Nitro Pro 12 is not loading after a Windows 10 Pro update.  I have tried repairing the program, but something is blocking the repair.  I have also tried to uninstall Nitro Pro 12, but something is blocking the uninstalling as well.  I'm dead in the water, on a busy day.  Any suggestions anyone?

Hello @lloydmajor,

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

To further assist you, let us use our Clean-up Utility to uninstall your Nitro Pro 12 by referring to these steps:

1. Clear the content of the directory under C:\users\your_username\Appdata\local\temp. For whatever reason, not all temp files automatically remove themselves and is NOT usually caused by Nitro Pro files.

2. Download and run our Clean Up utility to uninstall your Nitro Pro: http://install.nitropdf.com/professional_12163574/install-cleanup/install-cleanup.zip 

NOTE: This clean-up tool will erase any existing signature files within Nitro so please save them to another location before using the clean-up tool in order to keep them. Please see this link for backing up custom stamps/signatures: http://kb.gonitro.com/knowledgebase#/search/stamps/000001686 

3. 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.

4. Download and install Nitro Pro 12.16 using below offline installers:

x32 http://install.nitropdf.com/professional_12163574/en/retail/nitro_pro12_ba_x86.msi
x64 http://install.nitropdf.com/professional_12163574/en/retail/nitro_pro12_ba_x64.msi

If you are not sure which to pick, this will help: http://kb.gonitro.com/knowledgebase#/search/64/000001874 

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

If something is still blocking the uninstall and reinstall of your program, kindly provide a screenshot of the message you are receiving so I could my resources.
 
Thank you very much in advance and I am looking forward to hearing back from you.
