[Open Babel] obminimize MMFF94 error on Windows

[Tuong Vu T. H. <tuo...@ut...>]

hi all,
I run this command on windows: obminimize -n 2000 -c 1e-4 -sd -ff MMFF94 test.mol2 and got the following error:

==============================
*** Open Babel Error  in OpenBabel::OBForceFieldMMFF94::ParseParamFile
  Cannot open parameter file

I used the lastest version of openbabel 2.2.0.

Thanks in advance,

Tuong
