InnoDB錯誤MySQL的Windows 8

Question

我剛剛從Windows 7升級到Windows 8，但很多設置或文件已更改，我不能再連接到MySQL數據庫。

以下是錯誤我得到：

1. 我能做些什麼讓我的數據庫，並再次運行？

非常感謝所有幫助！

最可能的解釋是，Windows 8升級修改了MySQL數據目錄的權限。

從錯誤信息，它看起來像你的InnoDB的數據目錄可能是C:\Program Files\MySQL\MySQL Server 5.5\data

使用Windows資源管理器瀏覽到該目錄，右鍵點擊，打開屬性，然後單擊安全選項卡上。 MySQL服務正在運行的服務帳戶需要具有對該目錄的完全訪問權限（所有權限）。當你點擊編輯時，有兩列複選框允許和拒絕...完全控制，修改，執行&等）

（注意：我沒有運行Windows 8.在我的Windows 7上系統，數據目錄是C:\ProgramData\MySQL\MySQL Server 5.5\data\）
