This page has links to various Factoring software that I have compiled from source for Windows in 64bit and 32bit using Visual Studio 2010. Benchmarking information is provided on the Benchmarking Page.

Note: You may need to download and install a Microsoft Visual C++ Redistributable Package if the application does not work when you try to run it. For software compiled in 2011 or newer, download the Visual C++ 2010 Redistributable Package for 32bit or 64bit software. For software compiled in 2009, download the Visual C++ 2008 Redistributable Package for 32bit or 64bit software.
