I found this Stackoverflow article: http://stackoverflow.com/questions/1741933/detect-64-bit-or-32-bit-windows-from-user-agent-or-javascript which says that the following code deployJava.isWin64OS = function() { return navigator.userAgent.indexOf('WOW64')>-1 || window.navigator.platform=='Win64'; }; will return one of these: 64 bit MacOS + 64 bit Safari or 32 bit Chrome: window.navigator.platform=MacIntel 32 bit windows + safari: window.navigator.platform=Win32 64 bit Windows + 64 bit IE: window.navigator.platform=Win64 window.navigator.cpuClass=x64 64 bit Windows + 32 bit IE: window.navigator.platform=Win32 window.navigator.cpuClass=x86 64 bit Windows + 32 Firefox (or Chrome): window.navigator.platform=Win32 32 bit linux mint (i686) + firefox: window.navigator.platform=Linux i686 64 bit Ubuntu (x86_64) + 32 bit Chrome: window.navigator.platform=Linux i686 64 bit Ubuntu + 64 bit Epiphany: window.navigator.platform=Linux x86_64 In the ambiguous cases, you can get additional information by checking for flash. Because Adobe doesn't support flash player on x64 browsers, if detection is successful then it is definitely a 32 bit browser, if not, then the request came from either a 32 bit browser without flash plugin or from a 64 bit browser.
