How to find out if an installed Eclipse is 32 or 64 bit version?
Hit Ctrl+Alt+Del to open the Windows Task manager and switch to the processes tab.
32-bit programs should be marked with *32
.
Open eclipse.ini
in the installation directory, and observe the line with text:
plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.0.200.v20090519 then it is 64 bit.
If it would be plugins/org.eclipse.equinox.launcher.win32.win32.x86_32_1.0.200.v20090519 then it is 32 bit.
Help -> About Eclipse -> Installation Details -> tab Configuration
Look for -arch
, and below it you'll see either x86_64
(meaning 64bit) or x86
(meaning 32bit).
