无法安装Visual Studio LightSwitch 2011

Question

我想为Visual Studio Lightswitch 11试用90天的试用版，但我无法安装它。

我已从Microsoft下载站点下载完整的ISO安装程序。

错误的安装程序安装的显示器是： 安装程序无法安装以下组件： 微软的Visual Studio LightSwitch的2011 - ENU

的日志文件显示以下内容：

这是或者没有Visual Studio安装并更新到SP1。

我目前正在运行Windows 7 Ultimate x64 SP1。

任何帮助，非常感谢。

我的确找到了解决此问题的办法： 首先完成系统的完整备份，因为Microsoft卸载程序会告诉您在运行它们后可能无法正常运行。

下使用卸载： Visual Studio 2010的卸载工具 - http://archive.msdn.microsoft.com/vs2010uninstall 任何遗骸的.NET Framework 4客户端配置文件中。 -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的剩余部分被删除。 然后我开始全新安装Visual Studio 2010，然后安装SP1。 成功后，我从MSDN安装Visual Studio LightSwitch 2011，安装成功。
