我正在尝试在 Windows 7 Professional 上安装 Visual Studio 2013 Express，但我被困在 Web 平台安装程序 5.0 中：
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。我安装了其他可能与开发相关的软件，但我对这些东西还很陌生。我安装了 XAMPP，还有一些与开发相关的非 Microsoft 软件。我安装了 SQL Server 2012 Enterprise（完整版），但我已将它们设置为手动启动，因为它们阻止我启动 Apache Web 服务器。任何帮助或指导我都可以看看！
以下是（我认为）日志的相关部分：

您无需费力尝试解决有时不稳定的 Web 平台安装程序，而是可以直接从 Microsoft 提供的 ISO 进行安装：这里。另外，您可能需要检查您是否使用的是 Windows 7 SP1，因为这是此版本的最低要求，而不是标准 Windows 7。
