DeanP888 Posted November 14, 2019 Report Share Posted November 14, 2019 I purchased Nitro Pro 13 in Sept 2019. Installed it immediately on my Surface Pro. Then replaced my Surface Pro in Nov and re-installed NP13 on the new device. The new Surface Pro was a dud and also had to be replaced. I have now installed NP13 on my 2nd replacement but can't activate it because I have reached the maximum number of installations. I've tried using the 'activation portal' but the serial number comes up as 'invalid' because it seems that this portal doesn't support the latest version of Nitro Pro. I need some help to de-activate the 2x previous installations so that I can activate NP13 on my new device. Thanks, Link to comment Share on other sites More sharing options...
