Well, I believe Win2k3 Server x64 has a 32-bit compatibility mode that
it is using to run setup.exe. Self-modifying code would explain why DEP
would kill the program, but does that explain why CVS setup.exe is
getting killed but 2.510.2.2 isn't? It looks like autoload.c hasn't been
changed since 2004...
