丟失d3dx9-43.dll解決方案

在網上搜了下，有很多人遇到這種問題。
有的朋友安裝Microsoft C++ 2005 組件和安裝 DirectX 9.0c可以解決。但是我的win7 64位就是死活安裝不上9.0。
安裝 DirectX 就報錯，提示“發生內部系統錯誤 請參考Windows檔案夾中的DXError.log和DirectX.log以確定是什麼問題”。
開啟DirectX.log看到如下內容：

顯示都是have been installed already，意思就是都已經安裝。

又試了好多辦法，例如金山毒霸的電腦醫生“丟失d3dx*-**.dll”。還是無果，同樣安裝DirectX失敗。
又試了DirectX隨意卸，只不過卸載DirectX需要註冊碼，找了半天也沒找到。
不過功夫不負有心人，最終還是解決了，下面送上解決辦法。

解決方案：

1.首先安裝Microsoft Visual C++ 2005，然後安裝DirectX June 2010 SDK。一般情況下安裝好後就可解決問題。
2.如果遇到無法安裝DirectX，或者安裝報錯，或者是安裝後還是無法進行遊戲，那麼請使用DirectX修複工具 V2.5 線上修複版，檢測並修複。就可以解決問題。

丟失d3dx9_27.dll解決方案

當運行程式或者遊戲時，系統彈出錯誤提示“ 找不到d3dx9_27.dll ”,或者“ 沒有找到d3dx9_27.dll ”時，說明您系統中缺失這個dll檔案或者該dll檔案沒有被註冊，您需要下載該檔案將其解壓到相應目錄並註冊它。解決找不到d3dx9_31.dll或缺少的問題。

dll檔案如何安裝使用？
通常是將 dll檔案複製到“ X:/Windows/system32 ” (X代表您系統所在目錄盤符，如：C:/Windows/system32 ) 目錄下。

有些 dll檔案需要手動註冊一下才能使用，手動註冊方法：
1.將對應版本的 dll檔案複製到“ X:/Windows/system32 ” (X代表您系統所在目錄盤符，如：C:/Windows/system32)目錄下。
2.在開始菜單中找到“運行(R)” 或者按快速鍵 Win+R 。
3.在“運行(R)” 中輸入 “ regsvr32 d3dx9_27.dll” (不含雙引號) 斷行符號即可。
