Java not working -

Java not working -

i switched java 7 java 6 , java not working me @ all. have made sure java 7 uninstalled, , have correctly installed java 6 (it appears in command panel , everything). have made sure environment variables pointing right locations well.

for reason though java broken. typing in java version command prompt reveals this

error: not open `c:\program files\java\jre7\lib\amd64\jvm.cfg'

i have tried scouring registry traces of java 7, cannot find anything. know doing wrong here? thanks!

edit

now java version reveals

exception in thread "main" java.lang.noclassdeffounderror: version caused by: java.lang.classnotfoundexception: version @ java.net.urlclassloader$1.run(urlclassloader.java:202) @ java.security.accesscontroller.doprivileged(native method) @ java.net.urlclassloader.findclass(urlclassloader.java:190) @ java.lang.classloader.loadclass(classloader.java:306) @ sun.misc.launcher$appclassloader.loadclass(launcher.java:301) @ java.lang.classloader.loadclass(classloader.java:247) not find main class: version. programme exit. edit 2

ok....sorry. typing java version instead of java -version.

please forgive ignorance.

go start -> rightclick on computer -> properties then, in left pane, click on advanced scheme settings. within tab advanced, click on environment variables... right @ bottom of window. in upper pane, click on path -> edit , add together next line text popup shows up:

;%path_to_java%\bin

where replace %path_to_java% path java installation (including jre6 or that)

don't forget semicollumn if there in box, also, dont delete that, set path right behind that, no spaces.
