    • 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 openchrom -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 openchrom -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

OpenChrom® is an open source software for chromatography, spectrometry and spectroscopy and based on the Eclipse Rich Client Platform (RCP). Data from different systems can be imported and analyzed, hence it’s a vendor independent software.

Generally, it supports handling . Designed to analyze data from analytical pyrolysis, called Py-GC/MS, it has a strong focus on chromatography and nominal mass spectrometry.


  • Native handling of GC/MS, GC/FID, HPLC-UV/VIS, FTIR, PCR and NMR data.
  • Analyze data from analytical pyrolysis, Py-GC/MS.
  • Methods for peak detection, integration, identification, quantitation and reporting.
  • Internal (ISTD) and external standards (ESTD) for quantitation purposes.
  • Filters to help optimize the measurements and calculate key values of the chromatographic data and help to point out problems like shifted retention times or degraded columns.
  • Helps detect and identify peaks in a GC/MS file and to transfer these peaks to its corresponding GC/FID measurement for quantitation purposes.
  • Works in target screening (TS) and non-target screening (NTS) mode.
  • Extensible with plugins

OpenChrom® is tailored for data analysis purposes including processing, visualization and reporting. The implemented batch-processing features allow high-throughput evaluation. A continuously growing portfolio of processing and analysis procedures is provided. Extensions are welcome, as OpenChrom® is open source and uses a flexible approach, which allows others to implement their own methods, algorithms, filters, detectors or integrators.

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.
