Under Windows and Mac OS X, stand-alone executables built with older versions of PLT Scheme (usually with DrScheme) require a set of dynamic libraries. Since version 350, distribution executables created by DrScheme include all dynamic libraries.

The download page provides installers for the dynamic libraries for version 301 and earlier. If you build executables with version 301 or earlier, feel free to re-distribute the dynamic-library installers with your own applications, or direct users to our download page.
