# Installation Guide

## Upgrading

Note: Close any running instances of the simulator before upgrading.

### Windows

When upgrading from version 1.0, please first uninstall the version 1.0. The application name has been changed from EoUSI_Simulator to Verasonics_EoUSI_Simulator.

When upgrading from version 1.1, it should not be necessary to uninstall the old version first; Windows will uninstall the old version during the install.

### macOS

Delete the previous install before proceeding to the installation section.

For version 1.0, the install location is `/Applications/EoUSI_Simulator`. For version 1.1 and later, the install location is `/Applications/Verasonics_EoUSI_Simulator`.

## Installation

1. After downloading the installer as a .zip file (Available on Essentials of Ultrasound Imaging Simulators) extract its contents by unzipping the folder.
2. Find the `Verasonics_EoUSI_Simulator_Installer` file within the unzipped folder and double-click on it. This launches the installation window.
3. In the installation window, it is recommended that you accept the default installation location for the EoUSI Simulator and MATLAB Runtime. The installer checks if the MATLAB Runtime is already installed; if not, it will download and install the appropriate version. Note that this is a free distribution available for download on the Mathworks website. NOTE: The installation window may take a while to appear. Please wait and do not click on the icon repeatedly, as this may delay the installation even further.
4. Click the Start Installation button. The installation should start immediately.
5. Once the installation is complete, the installer may display additional steps for configuration. Skip these instructions and simply close the installation window.
6. See the Verasonics EoUSI Simulator User Manual for further instructions.
