Deployment Method:

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

1. Enter Your Internal Repository Url

(this should look similar to

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 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 crystalexplorer -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 crystalexplorer -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

CrystalExplorer is a versatile and powerful tool for investigating intermolecular interactions and packing in crystalline materials using the full suite of Hirshfeld surface tools and ab initio quantum mechanical calculations. It can be used to investigate many areas of solid-state chemistry including:

  • Intermolecular interactions
  • Polymorphism
  • Effects of pressure and temperature on crystal structures
  • Single-crystal to Single-crystal reactions
  • Analyzing crystal voids
  • Structure-property relationships

By mapping the ab initio quantum mechanical property densities and other distance- and curvature-related metrics on Hirshfeld surfaces, CrystalExplorer provides unique insights into the in-crystal environment.

A recent feature in this version is the ability to display and quantify voids in crystal structures.

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.
