How can I find out if a given program is 64 or 32 bit version? I can't to do it by simply looking at where it's installed, since some programs need no installer and may be put anywhere.
Here, no process explorer will help me, since the application refuses to start.
Reason why I need it: My new eclipse installation fails to load "jvm.dll" just like here. I'd bet I'm using 64-bit versions of both eclipse and JVM, but I'm slowly getting unsure.
