To configure Eclipse to use specific JVM you have to modify configuration file for your eclipse (usually eclipse.ini). Add following lines just before the line which says “-vmargs”. -vm D:\TOOLS\Java\JDK6-32bit\bin\javaw.exe {this should be the path to your desired JDK bin\javaw.exe }

I switched to Windows 7 64 bit few months back and I upgraded all my tools/SDKs to 64 bit versions including JDK.

And set the following environment variables in Windows JAVAHOME=path to the folder where JDK(32bit) is installed PATH=add path to bin folder of your JDK(32bit)
