Answer 1

Make sure your JDK Path variable is directing to the \bin folder and is at the top of the list.

If there's any other entry that has a file called java (such as C:\ProgramData\Oracle\Java\javapath) it will run the command against that file instead of the java file in your JDK. There's no need to reinstall the entire JDK unless your files are corrupt or damaged for some reason.

Answer 2

1. Uninstall Java from machine
2. Check Java folder is deleted from Program Files
3. Check Registry does not have any instance of Java
4. Open system Variables and delete the ONLY java path from PATH
5. Now install the new version again.
6. Set the Path in System Variables.

This process cleans up all the traces of java and then install fresh java.

Note: This issues occurs when there is multiple installation and uninstall done.

Answer 3

Reinstall JDK and set system variable JAVA_HOME on your JDK. (e.g. C:\tools\jdk7)
And add JAVA_HOME variable to your PATH system variable

Type in command line

echo %JAVA_HOME%

and

java -version

To verify whether your installation was done successfully.

Answer 4

I had to remove the Common Files javapath from the 'Path' that was conflicting, in order to make it work. Now thankfully the java -version works just fine.

C:\Program Files (x86)\Common Files\Oracle\Java\javapath

Answer 5

In my case the regedit information was correct and the problem was solved by doing the below:

1) setting JAVA_HOME to jdk - set JAVA_HOME=C:\Program Files\Java\\bin 2) setting PATH to jre - set PATH="C:\Program Files\Java\\bin"

Answer 6

I had a similar issue after installing the java 10.0

To fix this go to Advance System setting --> path and remove

C:\ProgramData\Oracle\Java\javapath;
