I have Windows 7. I downloaded Movie Maker and when I tried to open it, it says: "Sorry, Movie Maker can't start. Make sure your computer meets the minimum system requirements before trying to start Movie Maker again, and then try to update the driver for your video card if Movie Maker still doesn't start."

I looked at the system requirements and I updated Windows and the driver for my video card is on automatic update so I think I have all of requirements now but it still says the same thing when I try to open it.
