I don't think you've mentioned what version of Windows you are using or its 'bitness'.
It may not work in current versions of Windows such as Win 10 or if you have 64-bit.
Well I would try once more using a new copy from the link I gave but I doubt it will work.
64-bit Windows wasn't around in 2001 AFAIK and there is no reaqson for MS to update that DLL now.
I think you are going to need to rewrite the relevant code
