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 wimlib -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 wimlib -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

wimlib is an open source, cross-platform library for creating, extracting, and modifying Windows Imaging (WIM) archives. WIM is a file archiving format, somewhat comparable to ZIP (and many other file archiving formats); but unlike ZIP, it allows storing various Windows-specific metadata, allows storing multiple "images" in a single archive, automatically deduplicates all file contents, and supports optional solid compression to get a better compression ratio. wimlib and its command-line frontend wimlib-imagex provide a free and cross-platform alternative to Microsoft's WIMGAPI, ImageX, and DISM.

Among other things, wimlib:

  • Provides fast and reliable file archiving on Windows and on UNIX-like systems such as Mac OS X and Linux.
  • Allows users of non-Windows operating systems to read and write Windows Imaging (WIM) files.
  • Supports correct archiving of files on Windows-style filesystems such as NTFS without making common mistakes such as not properly handling ACLs, file attributes, links, and named data streams.
  • Allows deployment of Windows operating systems from non-Windows operating systems such as Linux.
  • Provides independent, high quality open source compressors and decompressors for several compression formats used by Microsoft which are not as well known as more open formats, and are prone to be re-used in different applications and file formats (not just WIM).

wimlib is distributed either as a source tarball (for UNIX/Linux), or as ready-to-use binaries (for Windows XP and later). The software consists of a C library along with the wimlib-imagex command-line frontend and its associated documentation.

NOTE: This is an automatically updated package. If you find it is out of date by more than a week, please contact the maintainer(s) and let them know the package is no longer updating correctly.

From: The license is distributed in the ZIP files.

wimlib (meaning all programs, scripts, libraries, documentation, and other files
that are part of the wimlib project -- not just the "libwim" library) may be
redistributed and/or modified under the terms of the GNU General Public License;
either version 3 of the License, or (at your option) any later version.  A copy
of this license can be found in the file COPYING.GPLv3.

Also, when not prohibited by a third-party software license, libwim (the library
portion of wimlib) may be redistributed and/or modified under the terms of the
GNU Lesser General Public License; either version 3 of the License, or (at your
option) any later version.  A copy of this license can be found in the file
COPYING.LGPLv3.  This is offered as a "dual license", meaning that you can
choose either this LGPLv3+ option or the above-mentioned GPLv3+ option.

In either case there is NO WARRANTY, to the extent permitted by law.


NOTE! The reason for the "when not prohibited by a third-party software license"
condition on the LGPL option for libwim is that libwim can optionally be linked
to the third-party library "libntfs-3g", which is licensed under the GPL.
Usually the GPL is interpreted in a way that means that any binary that uses a
GPL library must be licensed under the GPL as well, not (for example) the LGPL.

Therefore, if your build of libwim links to libntfs-3g, then you can't choose
the LGPL option.  You may choose the LGPL option for Windows builds of libwim,
since they don't link to libntfs-3g.  Likewise, you may choose the LGPL option
for UNIX builds of libwim that were built with './configure --without-ntfs-3g'.

NOTE! The file COPYING.CC0 contains a public domain dedication.  This public
domain dedication does not apply to wimlib as a whole, but rather to individual
source code files which the author(s) have elected to place into the public
domain, as noted in the corresponding file headers.  As usual, such code carries
NO WARRANTY, to the extent permitted by law.  See COPYING.CC0 for more details.

To verify the files:

1. Please go to the project site - and download the correct version and architecture of the EXE file;
2. Use Get-FileHash -Path <FILE TO VERIFY> to get the file hash value from both the official release (downloaded in step 1 above) and the file from the package and compare them;

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.
