Open CMD and enter the following (including the "" if there is a space within the path):
"C:\Program Files (x86)\Java\jre6\bin\java.exe" -jar "C:\Users\usernameofyou\Downloads\FooBMA.jar"
while replacing the first path with the path to your java.exe and the second with the path to this .jar file. Once set up you can simply create a .bat file with
"C:\Program Files (x86)\Java\jre6\bin\java.exe" -jar "C:\Users\usernameofyou\Downloads\FooBMA.jar" run
in it to run the authenticator (with your paths of course...).
