Thanks Guys! It's working now.

I had tried some of the other script methods ie: GetFileVersion but it hadn't worked.

I've given up on the vplogon.bat method and debuged my read value problems. It's working like a charm now.

I'll include the code in case it helps someone else out in the future.
Almost all of it was pieced together from other members scripts. Thanks to all of you..
