Thanks Breck,
I am looking at the object, When the same line of code worked before and then failed I knew it had to be in the PB code somewhere. I have gone through the code stepping through on the XP and Win 7 machines simultaneously and so far all the variables and settings are identical until it hit's the 2nd isvalid statement. I was thinking it would be a wow3264node registry issue somewhere, but I have been unable to locate it as of yet. I have compared all the object variables and they are the same. The only thing different in 64 bit vs 32 bit that I'm aware of is the wow3264node so that was my main focus once I narrowed it down.
I'll let you know if I am able to isolate the issue.
VR,
jeff
