Our server OS is windows 2008 server enterprise edition, 64-bit and we want to use Apache HTTP server.

I cannot find any introduction about whether it can or not run on 64-bit machine. Please help.

Yes, it can. Both a 32-bit and 64-bit build will work on a 64-bit machine/OS (with suitable libraries of course).


The Apache Software Foundation has not released any official 64 bit binaries for Windows. However, it's open source so there is a third party unofficial 64 bit binary package for Windows. Same thing goes for PHP on Windows:

I'd personally go with the official binaries. It depends on what you are doing but performance increases can be negligible: http://www.scribd.com/doc/363677/Benchmarks-AMD64-in-32bit-mode-vs-64bit-mode-Ubuntu (on Linux anyways). Also looking quickly via Google there are some reports of problems with the unofficial 64 bit binaries.


You can download the 64 bit binaries from apache lounge. You will require the proper Visual C++ libraries. Currently the latest version can be found under http://www.apachelounge.com/download/ using VC14. The required Visual C++ redistributables will be those of VS 2013
