How do I stop 12 updating to 13

[greg@psg.com.au]

Hi - I have Nitro Pro 12 which keeps updating to Nitro pro 13 - once it updates it tells me my product is unlicensed and does not except the 12 license. How to I stay on 12 until I am ready to upgrade and buy a 13 license. I have to uninstall 13 and put 12 back each time.

Hello Greg,

We do not have an auto-updater. Please try completely uninstalling Nitro Pro from your machine and then reinstall Nitro Pro 12 from here: https://www.gonitro.com/nps/product-details/downloads

Once activated, please let us know if the error continues.
