Problem Installing the Latest Version

[Skyman5]

I am on Windows 10 and Nitro v 13.13.2.242 and tried installing the latest version - 13.15.1.282

The install failed and messed-up my existing installation, so I tried a system restore, which did not work. I then tried to uninstall, but Nitro was not even listed. I then tried the executable again to see if that would work. But when I click to execute I receive a box saying,

"We heard you want to leave...
Are you sure you want to uninstall Nitro?
We'll miss you"

It gives me two choices:
"Yes, uninstall Nitro" - If I choose that it does about a one second uninstall ( I have tried that twice) and then the box closes
"No, I'll stay" - If I choose that the box closes

Either way, nothing has changed and I can not open or use Nitro There are entries for Nitro in both Program files and Program Files (x86)--> Nitro --> Pro-->13

What should I do?

Hello @Skyman5,

Thank you for reaching out to us through our Community Forums and our sincere apologies for this inconvenience.

To further assist you, please run our Clean-up Utility to clear traces of previous installation 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. Kindly note Appdata folder is hidden and to unhide it, please refer to this article https://cybertext.wordpress.com/2012/05/29/cant-see-the-appdata-folder/ 

2. Download and run our Clean Up utility to uninstall your Nitro Pro: http://install.nitropdf.com/professional_13151282/install-cleanup/install-cleanup.zip 

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 13.15 using below offline installers:

x32 http://install.nitropdf.com/professional_13151282/en/retail/nitro_pro13_ba_x86.msi 
x64 http://install.nitropdf.com/professional_13151282/en/retail/nitro_pro13_ba_x64.msi

If you are not sure which to pick, this will help: https://kb.gonitro.com/knowledgebase#/search/64/000003790 

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

Thank you for choosing Nitro and I hope this helps!
