# Installing via Command Line Interface (CLI)

MODLR for Excel is distributed as an MSI (Microsoft Windows Installer) package, a common format for software installation on Windows systems.

If you prefer to install MODLR for Excel via command line instead of running the `setup.exe` provided, utilizing the `msiexec` command-line tool, which is built into Windows operating systems, allows for installations without relying on a graphical user interface, can be used for automated installations and provides flexibility in specifying installation parameters.

Make sure to make sure your CLI has administrative privledges before installation.

## Run `msiexec` Command

Execute the `msiexec` command followed by the path to the installer package (`/i` in cmd) or (`-i` in powershell) and any additional parameters you wish to specify.

```cmd
msiexec /i "MODLR for ExcelSetup.msi"
```

```powershell
msiexec -i "MODLR for ExcelSetup.msi"
```

:::warning
If you have previously installed the addin, you will need to uninstall it prior to installing the new version.

## Optional Parameters and Properties

You can include optional parameters and properties to customize the installation process. Here are some commonly used ones:

* `qn`: Performs a completely silent installation without any user interface.

* `TARGETDIR="installation_path"`: Specifies the directory where the MODLR for Excel add-in will be installed instead of the default location. Replace `"installation_path"` with the desired installation directory.

* For more advanced usage and additional parameters, refer to the [MSIEXEC Documentation](https://docs.microsoft.com/en-us/windows/win32/msi/command-line-options).

* For information on properties that can be specified when installing, refer to the [MSIEXEC Property Reference](https://learn.microsoft.com/en-us/windows/win32/msi/targetdir)

For example, to perform a silent installation and specify the installation directory:

```cmd
msiexec /i "MODLR for ExcelSetup.msi" /qn TARGETDIR="C:\MODLR\"
```

```powershell
msiexec -i "MODLR for ExcelSetup.msi" -qn TARGETDIR='"C:\MODLR\"'
```
