WordPress configure my MYSQL server.

I download my installer and proceed to install the word press to my computer and it works great, until the download has already finished and it reached the 14th component (MYSQL5.1).
I already got this following problems: it already stuck after I tried to cancel and uninstalling and reinstalling it. And I also try to restart but it still seems like it still doesn’t finish installing and it didn’t configure my MYSQL server. I have no idea why is this happening. Can anybody lend me a hand by helping me about this problem?
