Ok so it finally works but when it’s on the loading page it gets to 75% and then it closes out out of it completely..what do I do about that

Hi I recently been trying to download the Black dragon viewer and every time I run it and install I click to open and it tells me I cannot open the file, I don’t know why and I’m not sure what else to try to get it to work my pc is Windows 10 and I’m not sure if that’s the problem or what, but I can’t access black dragon and I’ve tried 6 times already.
