为什么我被阻止安装Visual Studio 2013 Express？

我正在尝试在Windows 7 Professional上安装Visual Studio 2013 Express，并且在这里使用Web Platform Installer 5.0：

We're sorry. The following products have failed to install. Visual Studio Express 2013 for Web (Default Locale) This product did not install successfully: The installation is blocked. Web Platform Installer 5.0 Log 

我不知道从哪里开始。 我还有其他的东西可以用来开发，但是在这个东西上我是非常新的。 我安装了XAMPP，还有一些与非微软开发相关的东西。 我安装了SQL Server 2012 Enterprise（完整版），但是我已经将其设置为手动启动，因为它们阻止了我能够启动Apache Web服务器。 任何帮助或方向是非常感谢，我可以看看！

这是什么（我认为）是日志的相关部分：
