I think java in windows just take one "-" before arguments, not two,
also the MuseLab .jar file has a dash in its name, the .EXE no, so try:
java -jar muse-lab.jar
java -jar muse-lab.jar -d32
I have seen this behaviour in more than one computer, and some other users have said the same
- in my laptop (windows 7 HP SP1 32 bit) it does not work (maybe its graphics chip does not support OpenGL)
- but in my desktop I have dual boot (windows 7 Ultimate 32bits and windows 7 - HP 64 bits) - so, the same graphics chip and Nvidea drivers installed are the same
muse-lab works fine in windows 7 - 32 but not in windows 7 - 64b. The java portion of the screen just shows a ligh gray background ... if I minimize muse-lab and maximize it again, the java portion (the big right side) shows the back of my screen, whatever is there.
The left portion (non java) works as expected: after connections all signals coming from muse, and after creating a visualization all signals available, but no graphics is shown after selection of any signal.
BTW, MuseLab is the only java app that does not work well in my computers.
