Implements installing of Chocolatey packages from the web using choco:// Protocol with choco-protocol-support.cmd (and Sudo).


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 web page 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.cmd which then processes the URL and runs Chocolatey's cinst.exe ("choco install" shim) with help from Sudo to install the package. Lets hope this functionality gets built into a future version of Chocolatey and then this package can be deprecated. UPDATE: Added to Chocolatey 1.0.0 milestone!


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!

Virus Scan Results

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.
