>I downloaded MSFT's SP4 install for these files but after installing it, it only installed msxml3.dll and msxml3r.dll (on an XP Pro machine) and on my PC (a W2K Pro machine) it did not update the msxml3a.dll file. My "guess" is that the msxml3a.dll file is not needed - it has the name "XML Resources" as does the msxml3r.dll file so maybe the "a" file is an older version that got on my machine somehow. I tried the function on the user's machine and it seemed to work - but then it worked 50% of the time for the user before so I will have to wait and see if it works 100% of the time.

It's supposed to handle that for you. Good luck.
