To uninstall Olex², run the following command from the command line or from PowerShell:


Deployment Method:


This applies to both open source and commercial editions of Chocolatey.

1. Enter Your Internal Repository Url

(this should look similar to https://community.chocolatey.org/api/v2/)

2. Setup Your Environment

1. Ensure you are set for organizational deployment

Please see the organizational deployment guide

2. Get the package into your environment

  • Open Source or Commercial:
    • Proxy Repository - Create a proxy nuget repository on Nexus, Artifactory Pro, or a proxy Chocolatey repository on ProGet. Point your upstream to https://community.chocolatey.org/api/v2/. Packages cache on first access automatically. Make sure your choco clients are using your proxy repository as a source and NOT the default community repository. See source command for more information.
    • You can also just download the package and push it to a repository Download

3. Copy Your Script

choco upgrade olex2 -y --source="'INTERNAL REPO URL'" [other options]

See options you can pass to upgrade.

See best practices for scripting.

Add this to a PowerShell script or use a Batch script with tools and in places where you are calling directly to Chocolatey. If you are integrating, keep in mind enhanced exit codes.

If you do use a PowerShell script, use the following to ensure bad exit codes are shown as failures:

choco upgrade olex2 -y --source="'INTERNAL REPO URL'" 

Write-Verbose "Exit code was $exitCode"
$validExitCodes = @(0, 1605, 1614, 1641, 3010)
if ($validExitCodes -contains $exitCode) {
  Exit 0

Exit $exitCode

- name: Install olex2
    name: olex2
    version: ''

Package Approved

This package was approved as a trusted package on 14 May 2024.


Olex² is a simple to use program containing numerous tools for the structure analysis and publication, including Fourier maps and voids calculation and visualisation, space group determination, calculation of esd's for almost any possible geometrical parameters, CIF translation to HTML and other documents, hydrogen atom placement and many others. The graphical user interface is the result of 10 years of striving to provide the best possible experience to modelling even the most challenging structures with ease. The software originated at Durham University and has been in active development since 2004.


  • Stereo visualisation
  • Full history of the structure - from solution - to the refinement
  • Structure analysis - pi-pi and other interactions, easy s.u. (esd) on many geometrical parameters calculation
  • Own olex2.refine structure refinement module
  • Seamless integration with Shelxl - switch between Shelxl and olex2.refine in no time
  • Integration with Platon software - every knowledge Platon has is unlocked
  • Multi-platform Windows-Linux-Mac (thanks to wxWidgets)
  • Superflip GUI, ShelXT, Sir and other structure solution programs at the push of the button
  • Postscript and bitmap (jpg, png etc) output to high resolution
  • Advanced tools for disorder modelling using rigid body refinemet
  • Structure reports (and CIF) - by managing metadata are always up to date even after a new structure solution!
  • Electron density maps (and they are live for contour maps)
  • Numerous drawing styles, including a few of predefined
  • Customisable main Menu and the GUI toolbar
  • Embedded Python and macro binding to the command line or interface elements

In cases where actual malware is found, the packages are subject to removal. Software sometimes has false positives. Moderators do not necessarily validate the safety of the underlying software, only that a package retrieves software from the official distribution point and/or validate embedded software against official distribution point (where distribution rights allow redistribution).

Chocolatey Pro provides runtime protection from possible malware.
