12 April 2012: Version 4.92 is out! MacOS X users now have a simple drag-and-drop install, and there is now a version for Windows! Of course, GNU/Linux users are still well-supported as always.
The new version introduces fundamental normal surfaces, boundary slopes for spun-normal surfaces, and more. You can read more about what's new, or go ahead and download the new version.
Other highlights of Regina include angle structures, census enumeration, combinatorial recognition of triangulations, and high-level tasks such as 3-sphere recognition and connected sum decomposition. Regina comes with a full graphical user interface, and also offers Python bindings and a low-level C++ programming interface.
See the users' handbook for a full list of features.

MacOS Version Installer Lion (10.7)
Snow Leopard (10.6) on modern 64-bit machinesDownload Snow Leopard (10.6) on older 32-bit machines
Leopard (10.5)Download
Most Snow Leopard users should be able to run the 64-bit Lion package. If your machine is very old, you might get an error message ‘You can't open the application "Regina" because it is not supported on this architecture’. In this case, you can run the 32-bit Leopard package instead.
Windows Version Installer Windows 7
Windows Vista
Windows XP (see below)Download
On some Windows XP machines, Regina will not start (“The application failed to initialize properly ...”). The problem seems to be an obscure missing DLL, and the error message is spectacularly unhelpful; one known solution is to install Python 2.x from python.org.
To keep the installation simple, most packages do not include the MPI (high-performance computing) utilities. If you need these, let Ben know and he can build you an MPI-enabled package.
