Version 13 not uninstalling

Kunal Gupta

Recommended Posts

I have a license for Nitro 12.  While setting up a new computer, I accidentally downloaded and installed version 13, and my serial number is not activating.  So i'm trying to unistall version 13, so I can install 12.  However, while trying to uninstall, I keep getting a message "Something is blocking Nitro from proceeding.  No action was taken as a system reboot is required."  I have rebooted multiple times, but am still unable to uninstall 13 to replace it with 12.  Please help.

Hi @Kunal Gupta,

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

Please try to uninstall Nitro Pro using our cleanup tool. This will remove all traces of Nitro Pro on the computer and the uninstall process is different from Windows uninstall process. 
Here are the steps:

1. Download Nitro cleanup tool from the link below:

2. Extract the cleanup utility then run the cleanup tool by double-clicking nitro-cleanup.vbs. A command window will appear during the cleanup process.
3. After the cleanup, restart the computer. 
4. Install Nitro Pro 12 by downloading a new installer from the link below:

https://www.gonitro.com/nps/product-details/downloads - Click the 'Download Nitro Pro 12' link. 

5. Once Nitro Pro 12 is installed, activate it by going to Help tab > About Nitro Pro > Activate. Enter your version 12 serial number then click on Activate.

Kind regards,
