Soo.. Let’s look at some common mistakes. Try work from top to bottom.

1. Using the false version. (The correct version would be 0.5.1.)
2. Forgot to extract the folder. (Be sure that you extracted the folder.)
3. No C++ redistributables installed. (Download them.)
4. The .dll could really be missing. (In this cause, it’s an error from someone, but not yours)

As long as you hope, you can.
