I did got a similar problem, i suggest you download a mySQL that is in a repack, or use like "WAMP" or "XAMPP" , couse they got custom MySQl's , so you only have to install them. Then run them as normal. Couse they are easy to use in windows vista. As i am running vista to, i did got the exact same problem, i fixed it but you will have to download reshacker and edit the source of the MySQL installation. But try using WAMP or XAMPP as your repack mySQL.
