I’ve been running this Mac Mini for about 7 years and a few years back when Google released the NIK Software photo edit tools for free I downloaded it, installed it and it ran fine. About 3 years ago I installed an SSD, reinstalled most of my software and am now trying to re-install the NIK package. I open the installer, click on the correct buttons and get the following message:
I’m currently running 10.11.6.
Any idea what could cause this? All the NIK .dmg installers give this error message.
