Well I can't say for sure, other than to point out there is a bit more
voodoo these days than the old copy the dll to system32 that caused
dll hell.

If it does work, then
1. Are you 100% sure you looked in the voodoo path Windows puts these
files into. (remembering another application may have installed the
library already)
2. Are you 100% sure you loaded the 2.1 library and it hasn't somehow
loaded an older client library?

As far as I know, they are always needed under 2.1.
