Sorry that my post is so vague, that I only wrote "crashes" on it. I'm not sure what other information that I can give to help figure out the problem.
I took your suggestion and compiled a minimal application, which only opens a window (just to check if SFML will work), and I still included all of the dlls with it. I tried it and the minimal application opens fine on the laptop now without any problems.
I thought it might be a problem with music, so I tried again without the music, but it still did the same thing as before. Any other ideas what I can try testing?
I wanted to make it run on Visual Studio, like 10 times when I first downloaded SFML, for like 2 days, but every time even when I followed the instructions for setting up SFML perfectly, from multiple tutorials, even from video tutorials, it never works; it just won't link correctly, because everyone's tutorial isn't the exact same set-up as my computer, so I gave up on Visual Studio and switched to MinGW... unless there's some better tutorial. But I'd really love if I could use VC++ instead, since MinGW is nice but it's not as user friendly.
