Note: Because BoostPro is closing its doors , we have discontinued our support of these free installers, but we have donated the installer source code to the community. The Boost community is currently looking for volunteers to carry forward the job of building installers. If you’d like to help, please post to the Boost Developer’s Mailing List .
