Startup error?

So, I just downloaded it last night, and I let it extract from the zip overnight. When I tried to boot it up today, the small black screen flashed up, and disappeared after awhile. I tried to reboot it after that, and the small black box shows up under an error message: “critical error C0000005 at address 54888C26”. The same thing happened when I tried to boot Godra Remastered. What does this mean, and how can I fix it?

i’m not a specialist here but formatting should do the job but its a last resort type of thing
