I simply ran the 32 bit JRE offline installer, but I believe any of the
installers will reproduce this problem.
Two files are installed in some cases, not in others.
For instance, when I ran the 32 bit installer on my 32 bit XP system I got
these files installed:
however when I ran the exact same 32 bit installer on my 64 bit Vista system,
they were not installed.
I've never seen files that install on one OS version but not another before,
so this was a surprise. It was suggested these are part of the new plugin
or the deployment toolkit, so if they contain critical functionality that is
now missing on 64 bit vista that's serious.
