Download Jmeter and execute the batch file (Jmeter\\apache-jmeter-2.6\\bin\\jmeter.bat). We get the error message in the console:

navigate to the url http://jmeter.apache.org/download_jmeter.cgi-->download apache-jmeter-2.11.zip, which is under binaries.
this error is occurring since Apache jmeter.jar is missing in bin folder
