How do I see if Eclipse is 32-bit or 64-bit?
1, if it is downloaded on the official website, look at the compression package name can be seen, only with Win32 words is 32, with win32-x86_64 the word is 64 bits.
What if you already have a lot of installed packages that can't be found?
2, find the Eclipse installation directory Eclipse.ini file Open, under the Launcher.library key, if the win32.x86 is 32 bit, if the win32.x86_64 is 64 bits.
