We are formally at version 4. The Windows installers are published on two release channels:
Only monthly releases are permanently archived. If you need to reproduce a result or stay on a known version, use a monthly release.
Downloading a release from the archive requires accepting the license agreements above.
Releases before 2026-10 have a single .msi installer, which is offered for every installer choice.
There are several flavors of ProteoWizard depending upon your intended use. If you are primarily interested in using the tools, the binary distributions for your platform are most likely what you want. If you are interested in using ProteoWizard as part of a software project you are developing, check out the code from our GitHub repository. Other packages are also on Teamcity.
Developers interested in building the ProteoWizard libraries for use in their own projects can build the repository with the .NET SDK, using build.bat on Windows or build.sh on Linux; the README describes the options.
