For those having problems installing Aurora, I found a way to make it work. Here’s how.
After downloading the Aurora HDR 2018.exe file, I right-clicked on it and chose ‘run as administrator’. Doing it that way, the installation went fine and the program opened without problems.
After that, I started the program, entered the registration details and it worked perfectly.
Keep in mind that Aurora only works on 64 bit computers so if you have a 32 bit, don’t even bother trying to install it.
