Standalone Executable

Edge Protect Tools can be used as a standalone application. The executable can be found in the tools/edgeprotecttools/bin directory of the Edge Protect Security Suite or Early Access Pack installation.

Installing From Sources

Alternatively Edge Protect Tools can be installed from the sources as a Python package. The source code is located in the tools/edgeprotecttools/src directory of the Edge Protect Security Suite or Early Access Pack installation.

Install Python on your computer. You can download it from https://www.python.org/downloads/. Set up the appropriate environment variable(s) for your operating system.

Installing Package

Make sure that you have the latest version of pip installed, use the following command.

$ python -m pip install --upgrade pip
