The c0000006 (in page io error) exception is an absolute indication that the network connection to the network share from which KIX32 was started was forcibly disconnected during the script. In other words: the script involved, or some outside force, does a "NET USE Z: /d" while your script is running.

Depending on how you start KIX32, you may be able fix the problem by using the "START /w KIX32.EXE" command.
