ACL2 on Windows

Windows users will probably want to do either of the following two things to run ACL2 on their systems. Thanks to David Rager for his help with this page, in particular the second item just below.

Fetch the ACL2 Sedan (ACL2s), which is an extension and distribution of ACL2 integrated with the Eclipse IDE. If you wish to use ACL2(s) without the Eclipse front-end, see the information about ACL2s in the installation instructions, which explains how to obtain and use a pre-built ACL2 binary for Windows, Linux, or Mac.
Use a Virtual Machine platform, such as VMware Player (free for non-commercial use) or Oracle Virtualbox (free even for commercial use) to install Linux, and then follow the normal installation instructions to install ACL2. As of 2014, at least a couple of our power users are very happy with this solution, as it provides first-class access to utilities relevant to maintaining the ACL2 system and books (like GNU Make and perl).

You are welcome to obtain a Windows installer for a previous ACL2 release, which mimics some of Linux and provides Emacs. We have successfully installed updated ACL2 binaries in such an environment.
