Ah - that has to be the *.DLL, then. I'm not absolutly certain at the
moment, and I'm not at all 'home' on Basic, but I think you should have
that - or a copy of any 32bit DLL's you use, in the SYSWOW directory - this
whole compatibility re-direction issue, is very confusing. This link may
help:

Your routines don't have to actually call anything in the filesystem, or
manipulate it in any way, to be subject to compatibility side-effects - this
is an effect of how 32bit app's are installed in the filesystem on this OS.
