I can confirm that all my settings far exceed that (1920x1080) and I was able to run this downloader on 4 other lesser machines, all running Win10 Pro 64bit.
That being said I was able to workaround this issue by using one of the other machines to download the files and then run setup.exe skipping the downloader issue.
I am not sure what was going on. I ended up removing the video cards and running just the onboard graphics. I removed all the drivers for the other cards, ran one monitor rather the my normal 5 monitor setup.
Anyway, if anyone has this issue in the future, try downloading to another computer then open the setup.exe file on the target PC and you should be able to complete the setup.
