Anaconda

About

Anaconda is a free and open-source distribution of the Python and R programming languages for scientific computing, that aims to simplify package management and deployment.

Version: 2020.02 (with Python 3.7.6)

Assumptions

This document assumes you are familiar with the use of a Windows Administrator Command Prompt. It also assumes your copy of the PSADT is preconfigured to write logs to C:\ProgramData\Logs.

Obtain Package Source

Download the installer from the vendor website.

Vendor Configuration for Silent Install

Information on silent installations can be found in the vendor documentation.

Bear in mind with a silent install the installation directory must be specified, and must be the last argument.

Please also be aware that for a Windows 10 installation, logged in users are given full permissions to the Anaconda3 install directory, and the install directory has been added to the system path. You will see many forum posts from people saying their Anaconda installation was incomplete or that the icons didn't display properly, which is resolved either by addressing the permissions as I've just described, or performing a user-based install. You may also encounter other issues from Group Policy and/or if your organisation uses AppLocker.

Deploy-Application.ps1

Please note the script contains Pre-installation logic to detect and uninstall any legacy version it encounters and logs the version number. It achieves this by searching the registry for the associated application as a keyword, then methodically running any version, ascertaining it’s Uninstall string, and calling it with the provided silent switches. If the application and version we want is already installed, the install will not proceed.

Relevant extracts from the script are as follows:
