Vista Bit Help PLEASE!

[Daniel_Microtest]

Several months ago I put together a small script "copyBIT.bat" which places BIT files in the required folders.
this has been running successfully on Windows XP rigs for a while now, however, due to Vista being as (un)popular as it is, I have been tasked with rewriting the same script to be used with Vista, with a required version for both 32bit and 64bit editions.
However, as I have just returned from paternity leave after the birth of my first baby girl, I have an extremely high workload to get through and just simply cannot meet the required deadline.
If anybody out there has a spare hour or two, please feel free to analyse my script and edit to to make it work as it should with Vista 32 and 64bit versions.
I will be most greatful.
