How do I tell whether my IE is 64-bit For that matter Java too

Question

Millions of questions already on the web about how to tell whether the OS is 64-bit  but not whether IE and or Java runtime is 64-bit   Some background   I installed 64-bit Win 7  and IE installed automatically with it from CD  I didn t download IE   I did download Java runtime   Mouseover tips in Control Panel Programs shows it as      Java 32-bit     Java TM  Control Panel   Then I went to http   java com en download manual jsp and that page says     We have detected you may be viewing this page in a 32-bit browser  If you use 32-bit and 64-bit browsers interchangeably  you will need to install both 32-bit and 64-bit Java in order to have the Java plug-in for both browsers   But I cannot tell in the aftermath whether my Java is 64-bit   Evidently the  Java TM  Control Panel  is  but I don t know if that s the same as the runtime    I m afraid to ask on the offical Java forums  because they re such a-holes    Also  how do I issue a command to the OS to tell whether this IE is 64-bit

For Java  from a command line   java -version   will indicate whether it s 64-bit or not   Output from the console on my Ubuntu box   java version  1 6 0 12-ea  Java TM  SE Runtime Environment  build 1 6 0 12-ea-b03  Java HotSpot TM  64-Bit Server VM  build 11 2-b01  mixed mode    IE will indicate 64-bit versions in the About dialog  I believe

In addition to what TaskManager shows  if you use ProcessExplorer from Sysinternals  you can tell when you right-click on the process name and select Properties   In the Image tab  there is a field toward the bottom that says Image  It says 32-bit for a 32 bit application and 64 bit for the 64 bit application

Rob Heiser suggested checking out your java version by using  java -version     That will identify the Java version that will be commonly found and used  Doing dev work  you can often have more than one version installed  I currently have 2 JREs - 6 and 7 - and may soon have 8     http   www coderanch com t 453224 java java java-version-work-setting-path  java -version will look for java exe in the System32 directory in Windows  That s where a JRE will install it    I m assuming that IE either simply looks for java and that automatically starts checking in System32 or it ll use the path and hit whichever java exe comes first in your path  if you tamper with the path to point to another JRE     Also from what SLaks said  I would disagree with one thing  There is likely slightly better performance out of 64-it IE in 64-bit environments  So there is some reason for using it

Select Help- About  for 64 bit   it would say version as 64 bit Edition   I see this in IE 9   may be true with lesser versions too

Normally  you run IE 32 bit  However  on 64-bit versions of Windows  there is a separate link in the Start Menu to Internet Explorer  64 bit    There s no real reason to use it  though   In Help  About  the 64-bit version of IE will say 64-bit Edition  just after the full version string    The 32-bit and 64-bit versions of IE have separate addons lists  because 32-bit addons cannot be loaded in 64-bit IE  and vice-versa   so you should make sure that Java appears on both lists   In general  you can tell whether a process is 32-bit or 64-bit by right-clicking the application in Task Manager and clicking Go To Process   32-bit processes will end with  32
