I believe Radoslaw was looking for 32 versus 64 bit on a Windows platform, since he is trying to use IBM Download Director. On the Windows platform I'm not sure it is quite as obvious as to whether we're running 32 or 64 bit. I found a Java directory under both Program Files and Program Files (x86).
Setting my PATH variable to c:\Program Files\Java\jre6\bin and running java -version, I get: C:\Program Files\Java\jre6\bin>java -version Picked up _JAVA_OPTIONS: -agentlib:c:\PROGRA~3\APPLIC~1\aternity\hooks\JAVAHO~1 java version "1.6.0_43" Java(TM) SE Runtime Environment (build 1.6.0_43-b01) Java HotSpot(TM) 64-Bit Server VM (build 20.14-b01, mixed mode) Setting the path to c:\Program Files (x86)\Java\jre6\bin and running java -version, I get: C:\Program Files (x86)\Java\jre6\bin>java -version Picked up _JAVA_OPTIONS: -agentlib:C:\PROGRA~3\APPLIC~1\Aternity\hooks\JAVAHO~2 java version "1.6.0_43" Java(TM) SE Runtime Environment (build 1.6.0_43-b01) Java HotSpot(TM) Client VM (build 20.14-b01, mixed mode) Without setting any PATH variable I get the same output as the first one (mentioning 64 bit). So it appears as though in the Windows7, Java 6 world, if it says it is 64 bit, it (hopefully) is, if it doesn't say what it is, it is running 32 bit.
