Get rid of the trailing backslash and especially the trailing semi-colon to deal with error java_home is not defined correctly -
C:Program FilesJavajdk1.8.0_91
By the way, you can display the current setting with the shorthand of typing "set" at a command prompt followed by the minimal number of characters needed, i.e. on my system:
set j
JAVA_HOME=C:Program FilesJavajdk1.8.0_144
