Download and install any dependency such as .NET, Visual C++ or SQL Server during your application's installation!
In this article you will see installation, usage, integration, details, and dependencies of Inno Setup Dependency Installer.

Inno Setup Dependency Installer


Inno Setup Dependency Installer can download and install any dependency such as .NET, Visual C++ or SQL Server during your application's installation. In addition, it is easy to add your own dependencies as well.

Installation and Usage

  1. Download and install Inno Setup 6.2+.
  2. Download the script from here or the Github repository.
  3. Open the extracted CodeDependencies.iss file.
  4. Comment out dependency defines to disable installing them in the example setup and leave only dependencies that need to be installed:
    • #define UseVC2013 <-- installed in example setup
      ;#define UseVC2013 <-- commented out and not installed in example setup
  5. Modify other sections like [Setup] [Files] [Icons] as necessary.
  6. Build setup using Inno Setup compiler.


You can include CodeDependencies.iss file into your setup by disabling compilation of the example setup before and calling the desired Dependency_Add functions:

#define public Dependency_NoExampleSetup
#include "CodeDependencies.iss"

; ...

function InitializeSetup: Boolean;
  // add the dependencies you need
  // ...

  Result := True;


You have two ways to distribute the dependency installers. By default, the dependency will be downloaded from the official website once it is defined as required in the CodeDependencies.iss file. Another way is to pack the dependency into a single executable setup like so:

  • Include the dependency setup file by defining the source:

    Source: "dxwebsetup.exe"; Flags: dontcopy noencryption
  • Call ExtractTemporaryFile() before the corresponding Dependency_Add function


The dependencies are installed based on the system architecture. If you want to install 32-bit dependencies on a 64-bit system you can force 32-bit mode like so:

Dependency_ForceX86 := True; // force 32-bit install of next dependencies
Dependency_ForceX86 := False; // disable forced 32-bit install again

If you only deploy 32-bit binaries and dependencies you can also instead just not define ArchitecturesInstallIn64BitMode in [Setup].

QuestionDependencies with multiple files Pin

How can I handle the situation where my dependent installers have multiple files rather than a single installer? My system needs to install some hardware drivers, but the driver files have their own dependent ini files which must be in the same folder.
