Now that I am using 64 bit version of the Apache HTTP Server, I also have to use 64 bit version of ModSecurity. I couldn’t find a 64 bit binary of the latest version (2.5.9 at the time of this writing), so I decided to compile it myself.
Anyway, I am posting this binary here for anyone else who needs it. I am currently using it with Apache 2.2.13 in Windows 7. It was compiled with Visual C++ 2008 (VC9), with libxml2-2.7.3 and lua-5.1.4.
