A modular InnoSetup script to download and install all available .NET Framework versions and much more

Introduction

This article contains a modular InnoSetup install script that downloads (if setup files don't exist locally) and installs various dependencies like .NET Framework 1.1/2.0/3.5/4.0/4.5 and others on 32-bit and 64-bit Windows.

Background

Once upon a time, I needed an installer for my .NET applications. I knew that I could use the "genius" ClickOnce installer, but in my opinion it has a bad interface and is not very handy. Then I came across a script for InnoSetup that had everything I wanted, but unfortunately it was only for .NET 1.1. So, I spent a few hours (became more over time) in InnoSetup and modified it to my needs.

Details

The source code is written modular being structured like this:

  • setup.iss - contains the basic setup where you include the modules (products) you need. They need to be included at the top like #include "scripts\products\dotnetfx11.iss" and then you only have to call their main function inside the [Code] part like dotnetfx11();
  • bin - contains the final output of the installer
  • src - contains the application files of your program
  • scripts
    • products.iss - contains the shared code for the product scripts. You only have to change the [CustomMessages] part and [Files] part (inclusion of isxdl language files)
    • isxdl - contains the downloader DLL for the setup (if there is something to download) and its language files (e.g. german.ini). This is the place where you can put your language files for the isxdl downloader in.
    • products - contains the scripts for products which are required by the application (e.g. .NET Framework 2.0)
      • dotnetfx11.iss - .NET Framework 1.1
      • dotnetfx11lp.iss - .NET Framework 1.1 Language Pack
      • dotnetfx11sp1.iss - .NET Framework 1.1 + Service Pack 1
      • dotnetfx20.iss - .NET Framework 2.0
      • dotnetfx20lp.iss - .NET Framework 2.0 Language Pack
      • dotnetfx20sp1.iss - .NET Framework 2.0 + Service Pack 1
      • dotnetfx20sp1lp.iss - .NET Framework 2.0 Service Pack 1 Language Pack
      • dotnetfx20sp2.iss - .NET Framework 2.0 + Service Pack 2
      • dotnetfx20sp2lp.iss - .NET Framework 2.0 Service Pack 2 Language Pack
      • dotnetfx35.iss - .NET Framework 3.5
      • dotnetfx35lp.iss - .NET Framework 3.5 Language Pack
      • dotnetfx35sp1.iss - .NET Framework 3.5 + Service Pack 1
      • dotnetfx35sp1lp.iss - .NET Framework 3.5 Service Pack 1 Language Pack
      • dotnetfx40client.iss - .NET Framework 4.0 Client Profile
      • dotnetfx40full.iss - .NET Framework 4.0 Full
      • dotnetfx45.iss - .NET Framework 4.5.2
      • ie6.iss - Internet Explorer 6
      • iis.iss - Internet Information Services (just a check if it is installed)
      • jet4sp8.iss - Jet 4 + Service Pack 8
      • kb835732.iss - Security Update (KB835732) which is required by .NET Framework 2.0 Service Pack 1 on Windows 2000 Service Pack 4
      • mdac28.iss - Microsoft Data Access Components (MDAC) 2.8
      • msi20.iss - Windows Installer 2.0
      • msi31.iss - Windows Installer 3.1
      • msi45.iss - Windows Installer 4.5
      • sql2005express.iss - SQL Server 2005 Express + Service Pack 3
      • sql2008express.iss - SQL Server 2008 Express R2
      • sqlcompact35sp2.iss - SQL Server Compact 3.5 + Service Pack 2
      • vcredist2010.iss - Visual C++ 2010 Redistributable
      • wic.iss - Windows Imaging Component
      • winversion.iss - helper functions to determine the installed Windows version including service packs
      • fileversion.iss - helper functions to determine the version of a file
      • stringversion.iss - helper functions to correctly parse a version string
      • dotnetfxversion.iss - helper functions to determine the installed .NET Framework version including service packs

Most of the time you need to tweak the setup.iss because of different Windows version / service pack version checks depending on your required dependencies.

If a dependency (product) is not installed, the script checks if the product's setup exists inside the dependencies directory which is configurable in products.iss. By default it is: .\MyProgramDependencies. If they don't exist there, it tries to download them (except for Windows Service Packs). This means a support for offline installing via CD or DVD is also possible.

The installation routine of the dependencies is automatic, and they run in quiet or semi quiet mode. Therefore no user interaction is needed (except for Internet Explorer 6). This setup script uses [CostumMessages] so that you can easily add multi-language support to your setup and easily configure settings (like the offline dependencies directory) without looking at the [Code] part.

Applications used for the script are:

  • Inno Setup - setup engine (version 5.5.4)
  • ISTool - extends Inno Setup but I just needed the isxdl.dll downloader (version 5.3.0)

Known Problems

If dependencies are needed, the required free hard drive size shown before installation is incorrect.

Points of Interest

Special thank goes to Ted Ehrich who created the .NET Framework 1.1 script. I am sure that this script will serve me in the future very well and I hope you may like it too.

I also wanted to thank the community for sharing many fixes and improvments. Thanks guys, please keep it up! You can now also easily fork and send pull requests at the official Github repository.

QuestionDependencies file name Pinmemberfandisus28-Feb-13 0:25 
Hi... First of all, I want to thank you very much because this post help me a lot. But somehow i still confused about the dependencies file. I need to include microsoft installer 3.1. I delved into the msi31.iss file and find out that if the file is not found, the setup will download the msi31 from the internet.
 
I've got the msi31 installer from visual studio. The name was "WindowsInstaller-KB893803-v2-x86.exe". And in the msi31.iss file, there was "AddProduct('msi31.exe', " line. should i modify the line or the file name, or perhaps i should not?
 
Thanks
