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 edecoder -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 edecoder -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

eDecoder is a plugin for the popular archiver 7-Zip. It enables 7-Zip to handle many different types of mailboxes (files that contain email messages) like archives. It also enables 7-Zip to handle email message files like archives. Thanks to eDecoder, you can easily extract an email message or only an email attachment from a mail base without using the email client that created that mail base. Moreover, eDecoder enables 7-Zip to open so-called web archive files (MIME HTML files, which usually have the extension MHT or MHTML), as well as to open or create UUE and XXE encoded files.

The eDecoder plugin also contains eSplitter. It's a special codec that helps 7-Zip pack text files containing binary data encoded using base64 and some other binary-to-text encoding schemes (for example, web pages saved in the MHTML format, email messages in the EML format, mail bases in the MBOX and TBB formats, illustrated e-books in the FB2 format, and many more) into 7z files more efficiently.

List of formats that can be opened in 7-Zip with eDecoder

  • MGS - used by Microsoft Office Outlook
  • TNEF - used by Microsoft Office Outlook (winmail.dat or ATT0001.dat files)
  • DBX - used by Outlook Express 5 and 6
  • MBX - used by Outlook Express 4
  • MBOX - used by the following applications:
    Mozilla Thunderbird
    Apple Mail
    Opera Mail
    and by many other email clients
  • TBB - used by The Bat!
  • PMM - used by Pegasus Mail
  • EMLX - used by Apple Mail
  • UUE, XXE
  • NTX - YEnc files
  • BIN - MacBinary files
  • HQX - BinHex files
  • WARC - Web ARChive files
