Update failed. I have Windows Vista Business. Kept getting parameter line 0. Told it to ignore then program became unstable and wouldn't open after update. Had to remove it. "This version addresses a few problems and features a few code rewrites to provide a much more stable program. The update should now go flawlessly. Please update through the integrated updater and post your results on the forums. The program should launch the new setup, show a progress bar with the status, then restart Malwarebytes' Anti-Malware and show a nice message stating that the program was updated. Please let me know if that is how it does it." So the answer is it failed miserably for me.
