我想尝试使用90天试用版Visual Studio Lightswitch 11，但我无法安装它。
我已从Microsoft下载站点下载了完整的ISO安装程序。
安装程序安装程序显示的错误是： 安装程序无法安装以下组件： Microsoft Visual Studio LightSwitch 2011 - ENU
日志文件显示以下内容：

无论是否安装Visual Studio并更新为SP1。
我目前正在运行Windows 7 Ultimate x64 SP1。
非常感谢任何帮助。

我确实找到了解决此问题的方法： 首先对系统进行完整备份，因为Microsoft卸载程序会告诉您运行它们后可能无法正常工作。
使用以下方法卸载以下内容： Visual Studio 2010卸载实用程序 - http://archive.msdn.microsoft.com/vs2010uninstall .NET Framework 4 Client Profile的任何遗留物。 -http：//answers.microsoft.com/en-us/windows/forum/windows_other-windows_update/how-to-uninstall-microsoftnet-framework-4-client/a38b6692-cf6f-413f-a903-9a7f7fb44930
完成后，删除了SQL Server或TFS的任何遗留内容。 然后我继续全新安装Visual Studio 2010，然后安装SP1。 成功后，我从MSDN安装了Visual Studio LightSwitch 2011，安装成功。
