I've seen the same thing on Vista 64-bit; if you use a system-wide
installation of ImageJ and JRE you get a 32-bit JRE unless ImageJ is
"run as Administrator".  This happens even if you specify the location
of the system's 64-bit JRE in IJ's run configuration.  The current
workaround is for unprivileged users to install their own copy of IJ
with bundled 64-bit JRE in their own ImageJ directory.
