I assume the problem is that you have the eldest DLL in system32.  You could
try to remove it, update it with the latest one - hoping that it is backward
compatible - or move it somewhere where only the C:\Python25 install will look.

system32 has a special role and is search after the directory of the calling
object (ie. exe or dll), but before anything else.  See
