In the Windows environment, it is important to understand the difference between an EXE file and an MSI file. Both file types are commonly used for software installation, but they have distinct characteristics and purposes.

An EXE file, short for executable file, is a common file format used for running applications or programs in Windows. It contains the necessary instructions and data to launch and execute a software application. EXE files are typically self-contained and can be run directly by double-clicking on them. They often require user interaction during the installation process, such as accepting license agreements or choosing installation options.

On the other hand, an MSI file, short for Microsoft Installer, is a file format used for software installation and maintenance in Windows. It is a database-like file that contains installation instructions, including files to be installed, registry changes, and other configuration settings. MSI files are designed to provide a standardized and consistent way of installing software, making it easier to manage and maintain applications across multiple computers. They can be installed silently without any user interaction, making them ideal for enterprise deployments.

Examples:
1. Installing an application using an EXE file:

• Download the EXE file from the software vendor's website.


• Double-click on the EXE file to launch the installation wizard.


• Follow the prompts to complete the installation, such as selecting the installation location or choosing additional components.

2. Installing an application using an MSI file:

• Download the MSI file from the software vendor's website.


• Open a Command Prompt or PowerShell window.


• Run the following command: msiexec /i path_to_msi_file.msi /qn


• The /i flag specifies that it is an installation, and the /qn flag makes it a silent installation without any user interaction.
