VI using ActiveX works in XP, loads in Win7 64 bit but crashes in Win7 32 bit.

I have a VI that works in windows XP, loads in Windows 7 64 bit (for editing only) but crashes Labview in windows 7 32 bit.  I know the code works, but I haven't tried it on this particular PC before so I'm assuming there's a configuration error somewhere, but dang if I can find it.

I've included a screen shot of the error and a copy of the VI in question.
