To enable the use of binary ICA in eeglab/Matlab running under Windows, do the following:

Step 1: 
Download ica.exe from the eeglab website (http://www.sccn.ucsd.edu/eeglab/) and store it somewhere in the scope of the matlab path and the system path

Step 2: Modify icadefs.m
Set the variable ICABINARY to "ica.exe" 

Step 3: Modify binica.m
Replace this line (section "run binary ica", about line 333)
	       
	eval_call = ['!' ICABINARY '<' pwd '/' scriptfile];

with these lines:

   %<ICA for Windows>
   % - modified by Stefan Scherbaum, 2006
   if(strcmp(computer,'PCWIN'))
       %find full path to enable start command to find ica.exe
       ICABINARY=which(ICABINARY);
       %generate path for batch script
       ICABAT=strrep(ICABINARY,'.exe','bat.bat');
       %generate batch file
       fid = fopen(ICABAT,'wt');
           fprintf(fid,'REM BATCHFILE FOR ICA.EXE, WRITTEN BY STEFAN SCHERBAUM\n');
           fprintf(fid,'REM DO NOT CHANGE - CODE GENERATED BY MATLAB!\n\n');
           fprintf(fid,'REM RUN ICA\n');
           fprintf(fid,[strrep(ICABINARY,'\','\\'),' < %%1 \n']);
           fprintf(fid,'REM CLOSE CMD WINDOW TO SIGNAL END OF ICA TO MATLAB\n');
            %fprintf(fid,'pause\n');
            fprintf(fid,'exit\n');
       fclose(fid);
       %use start to open new cmd window to show ica output
       % /wait lets matlab wait till cmd window closes after processing
       % /belownormal could be included to lower ica process priority to 
       %    continue doing other stuff in that machine
       eval_call=['!start /WAIT ' ICABAT ' ' pwd '/' scriptfile];
   else % UNIX and other system standard call
       eval_call = ['!' ICABINARY '<' pwd '/' scriptfile];
   end
   %</ICA for Windows>

Step 4: start binary ica via the GUI by selecting binica as method to run ICA
