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

1. Ensure you are set for organizational deployment

Please see the organizational deployment guide

  • 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. Enter your internal repository url

(this should look similar to

4. Choose your deployment method:

choco upgrade lazarus -y --source="'STEP 3 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 lazarus -y --source="'STEP 3 URL'"

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

Exit $exitCode

Lazarus is a free cross-platform visual integrated development environment (IDE) for rapid application development (RAD) using the Free Pascal compiler, which supports dialects of Object Pascal, to varying degrees. Software developers use Lazarus to create native-code console and graphical user interface (GUI) applications for the desktop, and also for mobile devices, web applications, web services, visual components and function libraries (.so, .dll, etc., for use by other programs).

The Free Pascal compiler supports a number of different platforms, such as Mac, Linux and Windows. Along with the customary project management features, the Lazarus IDE also provides features that includes but are not limited to:

  • A What You See Is What You Get (WYSIWYG) visual windows layout designer
  • An extensive set of GUI widgets or visual components such as edit boxes, buttons, dialogs, menus, etc.
  • An extensive set of non-visual components for common behaviors such as persistence of application settings
  • A set of data-connectivity components for MySQL, PostgreSQL, FireBird, Oracle, SQLite, Sybase, and others
  • Data-aware widget set that allows the developer to see data in visual components in the designer to assist with development
  • Interactive code debugger
  • Code completion
  • Code templates
  • Syntax highlighting
  • Context-sensitive help
  • Text resource manager for internationalisation (internationalization)
  • Automatic code formatting
  • The ability to create custom components

Lazarus inherits three features from its use of the Free Pascal compiler: compile speed, execution speed, and cross-compilation.

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.
