If what you pasted is copied right from the .bat file, then the problem is because you have accidentally combined the line beginning with 'set jvm_options' with the next line.
Insert a new line (press Enter) or two between the '-Xmx1792m' and the '::*--' characters.
Instead of:
set jvm_options=-XX:MaxPermSize=256M;-Xmx1792m::* ------------------------------------------------------------------------------ ::* do not configure below this point
you should have this:
set jvm_options=-XX:MaxPermSize=256M;-Xmx1792m ::* ------------------------------------------------------------------------------ ::* do not configure below this point
