If it's any consolation, no 64bit formats are supported, not just PE+.
Somebody's been rumoured to have worked (and then stopped working) on
x86_64 support, but I haven't found any traces of actual code yet.

OK, I'll tack it onto my todo list and see when I get to that.  It would
really be nice if setup64.exe wouldn't be as large as it currently is.

The initial unpacker stub is in assembler indeed, I haven't looked at it
in any detail.  However, I expect it either just works as is or it's
over my head anyway.
