這似乎還沒有造成問題，但這是我真正想了解的。基本上，我們有四個版本的產品：1.0（2.6.0.0），1.0.1（2.6.1.0），1.1.1（2.6.3.0）和1.1.2（2.6.4.0）。我們只是測試1.1.2的完整和補丁安裝程序。爲什麼Windows Installer以錯誤的順序安裝我的補丁變換？
我們看到的奇怪之處在於，當從1.0 - > 1.1.2應用補丁時，安裝程序的日誌顯示它首先選擇使用1.0.1 - > 1.1.2補丁變換，對我來說是愚蠢的，因爲它可以使用1.0到1.1.2的轉換。日誌如下：

那麼它爲什麼選擇先應用錯誤的轉換？我猜它應用它，因爲當它到達正確的轉換時，它知道產品版本已更新到2.6.4.0。
我注意到，在以前的設置文件夾下的補丁設計器中，順序確實是1.0.1,1.0,1.1.1。這當然不是確定Windows Installer運行修補程序轉換的順序嗎？！
如果有人知道這種行爲，或者可以指向正確的方向我非常感謝！ :)
謝謝！
更新
我認爲這已經成爲一個問題！ :(我認爲在更新File表時，不正確的轉換順序會導致問題，因爲它認爲它是從1.0.1 - > 1.1.2轉換的，所以它假定File表中的一行存在，只需要修改的時候，確實我們從1.0轉化 - > 1.1.2與該行不存在於表和需求增加
任何人有什麼想法
