When I installing nitro 12 trial, my system shows the message like "Your system is not modified permanently, please try again later". My system is installed with nitro 11 already. Kindly tell the possible solution for this.

Hello,

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

Installing Nitro Pro 12 removes Nitro Pro 11. If you would still like to install the trial, please try to completely uninstall Nitro Pro 11 manually and then install Nitro Pro 12 using the installers here  

I hope that helps!
