EXE Vs MSI: What are The Differences & Which is Better?

To install software on Windows, you need to download an installer on your computer. There are two most popular installation file formats .exe and .msi. Both formats serve the same purpose of installing software. However, a few differences make one better than the other in certain scenarios.

In this guide, we will compare the EXE file vs the MSI file side by side, explain their differences, and which to choose in what scenario. Let’s start!

What is an .EXE file?

.EXE is an executable file that can be run on your computer to install or launch a program. It is a self-extracting archive with the necessary files and instructions to install the software on your computer.

EXE files can be easily downloaded from the internet or installed using a storage device. To execute the file, you need to double-click it, and it will extract the essential files and launch the installation wizard.

What is an .MSI file?

MSI stands for Microsoft Installer (now called Windows Installer Package), a file format developed by Microsoft for installing software on Windows OS. These are database files with necessary information about software, including program files, registry keys, and settings.

They offer customized installation options suitable for enterprise environments where software deployment needs to be automated & centrally managed. Software developers use them to create and distribute software packages that can be installed on different Windows machines.

What are the differences between EXE and MSI files?

1. Installation process

The installation process of EXE and MSI files is similar. Both launch the installation wizard when initiated, guiding you through the installation process.

However, MSI files come with customizable options that are easier to automate for large-scale deployments.

2. Installation location

EXE files can be installed anywhere on your computer, including C drive, desktop, or any other location you choose.

However, the MSI file is typically installed using predefined paths specified in the package, and a copy of the installation database may be stored in the Windows Installer cache for future repair or uninstallation.

3. Installation options

Unlike EXE files, MSI files come with many customization options, such as selecting which program components to install, creating desktop shortcuts, or adding the program to the Start menu.

4. Software dependencies

EXE files can be standalone, but many still require dependencies like .NET Framework or Visual C++ Redistributables to run properly. Similarly, MSI files may depend on specific system components or libraries as they rely on Windows Installer services.

Regardless of format, installers often bundle or prompt installation of required components to ensure successful deployment.

5. Uninstallation

Programs installed via EXE or MSI can both appear in the Programs & Features list in Windows. However, MSI-based installs offer more consistent support for uninstallation, repair, and modification using built-in Windows Installer services.

This makes MSI packages especially useful in enterprise environments where clean removal and self-repair options are important.

6. Customizability

MSI files can be modified using several tools and technologies to include custom installation options, including choosing the software’s features, registry keys to change, or files to install or delete.

On the other hand, EXE files are generally preconfigured by the software vendor and can’t be easily modified.

7. Automation

MSI files are designed for automated software deployment and management. These files can be installed on multiple computers without user interaction; therefore useful for large-scale software deployments.

However, EXE files require user interaction to install and configure software on a Windows computer.

8. Security

Both MSI and EXE files can and should be digitally signed to verify authenticity and ensure the file hasn’t been tampered with. The signing process is identical for both formats and depends entirely on the developer’s implementation.

Unsigned files—regardless of format—pose a security risk. Always check for digital signatures before running any installer.

9. Size

MSI files contain more information & metadata about the software, including configuration data, dependencies, and installation options; hence are larger.

However, EXE files only contain the executable code and necessary resources for a software application.

.EXE file vs .MSI file: Which is better?

There can’t be one answer to this question, as choosing the file format depends on the needs and specific requirements of the installed software. Here are a few scenarios which can help you understand better:

• If you installing software that needs customization during installation, an MSI file is better as it comes with various customization options.
• If installing software that needs to be managed centrally across several computers in an organization, then you need an MSI file. You can use software deployment tools such as Group Policy to manage them.
• An EXE file is better if you use the software on a personal computer as it is less complex and easy to install.

To conclude, upon comparing the EXE file vs MSI file, it is evident that choosing one has its benefits or disadvantages. EXE file is useful for a single computer, whereas an MSI file is preferred for deploying software on multiple computers.

So, the choice depends on the software requirements you want to install.
