‘java’ is not recognized as an internal or external command, operable program or batch files.
This suggests that the system cannot find Java. You usually don’t need to add it to the system PATH variable manually, but since it’s not finding it, you can manually add it. First, find out where java.exe is installed. For example, on mine it’s at:
C:Program FilesJavajre7bin
it may be different on your computer so check to make sure.
Then go to Start -> right click on My Computer -> Properties -> Advanced system settings -> Environment variables. Then look at System variables, find the Path variable, click on Edit, and append
;C:Program FilesJavajre7bin
at the end of the Variable value. Note the semi-colon, as it separates the newly added from the existing. Then click on OK and see if this makes any difference. If you open a command line window and type ‘java’, it should print out a bunch of java options and should not report ‘not recognized’.
