John Schaaf 0 Report post Posted May 22, 2018 I am trying to install Nitro Pro 6 on a Windows 7 computer. This is the second computer and I have 2 licenses. The first computer installed and activated fine but on the 2nd computer I am getting an error message when I try to launch Nitro Pro. The window title is ERROR and the error message is "Originally licensed on a different computer". I have uninstalled and reinstalled with no success. Please help. Thank you, John.
