HI given that you have LSDYNA licenses it should able to solver directly from the installation, is this an acedamic version ? , can you able to check in the installation dir under win64 to see if you fnd any lsdyna_mpp or smp executables, if its not you may want to look for correct installation , the work around is to run the input file via LS-RUN as it might detect the solvers. 

Cheers, Ram
