Inno Setup 安装自动检测 .NET 环境安装解决方案大眼仔旭(www.dayanzai.me)发布。现在有越来越多的程序是基于 .Net Framework 环境开发的,而这类程序多数依赖 .NET 运行环境。作为在打包分发软件的时候,通过使用 Inno Setup 可以在安装包运行时自动检测电脑上是否安装 .NET 环境。毕竟有些用户是没有安装 .NET 环境,如果直接安装发现无法打开应用程序,就会给用户造成非常不可靠的感觉。

以下的检测方法是由 kybso 发布在 GitHub 社区并共享源代码,这里作一些解释引用:

添加 .NET 安装基本的函数及辅助方法:
在 [Setup] 段下引用几个辅助文件:

1

//import dependency for .net
//isxdl operation
#include "dependency\isxdl.iss"
//;TYPES AND VARIABLES
#include "dependency\products.pas"
//about .net versions
#include "dependency\dotnetfxversion.iss"

isxdl.iss — 引用了 isxdl.dll 并添加文件下载、安装函数
products.pas — 版本的安装过程
dotnetfxversion.iss — .NET 版本信息等相关函数

添加 .NET 版本引用及启动执行:

以 .net4.5.iss 为例,添加了版本的信息及下载地址等

[CustomMessages]
dotnetfx45_title=.NET Framework 4.5.2
dotnetfx45_size=68 MB

[Code]
const
    dotnetfx45_url = 'http://download.microsoft.com/download/B/4/1/B4119C11-0423-477B-80EE-7A474314B347/NDP452-KB2901954-Web.exe';

procedure dotnetfx45(minVersion: Integer);
begin
    if (dotnetfxspversion(NetFx4x, '') < minVersion) then
        AddProduct('dotnetfx45.exe',
            '/lcid ' + CustomMessage('lcid') + ' /passive /norestart',
            CustomMessage('dotnetfx45_title'),
            CustomMessage('dotnetfx45_size'),
            dotnetfx45_url,
            false, false, false);
end;

在 [Setup] 中添加要依赖的 .NET 版本:

1
2
3
4
[Setup]
//add .net4.5
#include "dependency\.net versions installation\dotnetfx45.iss"
#include "dependency\.net versions installation\dotnetfx46.iss"

添加自定义语言选项,如果安装包需要支持多语种,可以额外引用其它语言项进行选择。
