無法安裝Visual Studio LightSwitch 2011

Question

我想爲Visual Studio Lightswitch 11試用90天的試用版，但我無法安裝它。

我已從Microsoft下載站點下載完整的ISO安裝程序。

錯誤的安裝程序安裝的顯示器是： 安裝程序無法安裝以下組件： 微軟的Visual Studio LightSwitch的2011 - ENU

的日誌文件顯示以下內容：

這是或者沒有Visual Studio安裝並更新到SP1。

我目前正在運行Windows 7 Ultimate x64 SP1。

任何幫助，非常感謝。

我的確找到了解決此問題的辦法： 首先完成系統的完整備份，因爲Microsoft卸載程序會告訴您在運行它們後可能無法正常運行。

下使用卸載： Visual Studio 2010的卸載工具 - http://archive.msdn.microsoft.com/vs2010uninstall 任何遺骸的.NET Framework 4客戶端配置文件中。 -http：//answers.microsoft.com/en-us/windows/forum/windows_other-windows_update/how-to-uninstall-microsoftnet-framework-4-client/a38b6692-cf6f-413f-a903-9a7f7fb44930

一旦完成，SQL Server或TFS的剩餘部分被刪除。 然後我開始全新安裝Visual Studio 2010，然後安裝SP1。 成功後，我從MSDN安裝Visual Studio LightSwitch 2011，安裝成功。
