To uninstall (unofficial) choco:// Protocol support, 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 choco-protocol-support -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 choco-protocol-support -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

screenshot of choco-protocol-support

Implements installing of Chocolatey packages from the web using choco:// Protocol.


choco-protocol-support is designed for those who aren't comfortable with the Command Prompt or just don't like to type much. choco-protocol-support allows you to install Chocolatey packages by simply clicking choco:// URLs in your web browser. choco-protocol-support is also useful for support professionals who know the difficulty of getting end users to type in commands correctly. Now you can give end users a URL via e-mail or corporate software webpage to click and have a Chocolatey package installed!

If you like the convienance of this package, you should also check out Install Chocolatey Packages from your Web Browser which is very similar in concept as well as (unofficial) Chocolatey Shortcuts (Config). All three of these make installing Chocolatey packages very user friendly.


choco-protocol-support configures Windows to use choco://packagename URLs and pass them along to choco-protocol-support.ps1 which then processes the URL and runs "choco install" or "choco upgrade" to install or upgrade the package. This ability will be baked natively into a future version of Chocolatey and then this package can be retired.


Just click a choco://packagename URL on a web page and the package will install after one or two approval clicks.
Browser examples: Chrome | Firefox | Opera

Easy peasy, Chocolateasy!

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).

Sounds cool but where can I use it now?

You can install any Chocolatey package from the Chocolatey Community Repository website using Chrome with the help of BananaAcid's Chocolatey Appstore Theme for Chrome (unofficial)! Chrome Web Store direct link


  • 0.2 - Rewritten in PowerShell, changed use of cinst.exe to choco.exe (install) for Chocolatey v2 compatibility, sudo dependency removed as no longer needed, added version support, now checks for the package and uses choco upgrade instead of choco install when appropriate
  • - Removed Chocolatey dependency as Chocolatey v1.0 has been released and missed the 1.x milestone of becoming multi-instance aware and no new known goal. Added gsudo support.
  • 0.0.1 - Initial release.


  • Add parameters, install arguments, and source support (Going to need a LOT of difficult parsing for escaping!)
  • Add a config file that allows setting of default parameters, install arguments, source, etc.
  • Error checking for malformed URLs (Low priority, this resposibility should fall on the webmaster.)
  • Theoretically it's possible to add all choco install options and switches, but why?

This package has no dependencies.
