I can open royals by setting one of my 1080p monitors as main, and launching royals. I can change my main monitor back to my 1440p monitor while royals is in windowed mode and move the window to my 1440p monitor just fine. If I close royals, and try to open it again with the 1440p monitor as main, I get the -2147467259 error again as I was before. I have to repeat the process of booting up royals on my secondary 1080p monitor as main if I want to play. Thanks! tagging @Dave Deviluke as they wanted me to.
We believe to have fixed this issue, could you please try installing the latest setup from the website (added 30th Nov 11:40), and let us know if that fixes it for you?
Yeah it's fine now. Also hey, nice majoras mask @Matt I made the realistic majoras mask for the terrible fate cinematic, and also for the Time's End albums with Theophany
