If you have it already in your computer, yes you can use it but you need to change some line on the code.
So if you have it, you need to add these lines in the matlab function bst_duneuro.m at line 32.
% Install bst_duneuro if needed
[DuneuroExe, errMsg] = duneuro_install();
if isempty(DuneuroExe)
DuneuroExe = bst_fullfile(bst_get('BrainstormUserDir'), 'bst_duneuro','bin','bst_duneuro_meeg_win64');
errMsg= '';
end
