Unless it's possible to set these rights depending on whether a 32bit or
a 64bit process is run by the user I don't see how this would come into
play.  As I said, it's the exact same user and the exact same setup for
both 64bit and 32bit.

See my other mail, not that it elucidates the reason, but I think I've
pinpointed where it happens now.
