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 innounp -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 innounp -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

Inno Setup is a popular program for making software installations. Unfortunately, there is no official unpacker - the only method of getting the files out of the self-extracting executable is to run it. One piece of software that addresses this issue is Sergei Wanin's InstallExplorer, a plug-in for the FAR Manager that unpacks several types of installations, including Inno Setup (IS). But since it is not updated in a timely fashion, and so does not support the latest IS most of the time, this program was born.

The advantages over InstallExplorer are:

  • Innounp is open source and based on IS source. Therefore, it is more likely to support future IS versions.
  • It recovers portions of the installation script (.iss file), including the registry changes and the compiled Innerfuse/RemObjects Pascal Script, if available.

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.
