asp.net – Inno安装IIS安装和配置

这是我使用Inno Setup处理IIS(Internet信息服务)的完整代码.
它包含：

>安装.NET Framework 4
>安装/卸载IIS ASP.NET 4
>注册和删除网站/应用程序
>帮助用户帐户运行应用程序池
>帮助者获取网站的物理路径

它已经过以下Windows版本的测试：
XP专业版SP3 x86,2003 R2 x86,2003 R2 x64,Vista Ultimate x64,7家庭高级版x64,2008 R2 x64,2011 x64,8.1 Pro x86,10 Pro x64

一切都尽可能地被动完成,不会破坏任何现有的网站.

重要

这可能需要Inno-Setup的Unicode版本(我使用的是5.5.6(u)).
它还需要在x64机器上强制使用64位模式(否则注册表和文件访问将重定向到32位内容)：

.NET 4安装

将为Win XP / 2003安装.NET 4.0.适用于Vista / 2008及更高版本的.NET 4.6.
如果系统已包含.NET 4(Win 8/2012/10),则无效.
以下文件是必需的,必须包含在设置中：

> .NET 4.0 Web安装程序“dotNetFx40_Full_setup.exe”=> https://www.microsoft.com/en-US/download/details.aspx?id=17851
