windows 7 - How to find out if an installed Eclipse is 32 or 64 bit version?

Question

How can I find out if a specific Eclipse instance on my (Windows 7) PC is the 32-bit or 64-bit version?

I've checked the About screen and the maze of dialogs one can call from there, but I didn't find any clues.

Also, right-clicking eclipse.exe in Windows explorer and opening the properties dialog box didn't give any hints.

Answer 1

Hit Ctrl+Alt+Del to open the Windows Task manager and switch to the processes tab.

32-bit programs should be marked with *32.
