This problem generally occurs in windows when your "Java Runtime Environment" registry entry is missing or mismatch with the installed JDK. The mismatch can be due to multiple JDKs.

3. Go to: \HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\

4. If Java Runtime Environment is not present inside JavaSoft, then create new Key and give the name Java Runtime Environment.

5. For Java Runtime Environment create "CurrenVersion" string key and give appropriate version as value:

If you face this error in cmd with another error as "could not find runtime environment" after you have done all settings in Environment Variable. Then you just need to run jre.exe in your jdk folder and reinstall it and then recheck it by java -version command. Hope it will help you.

Answer 6

after adding the requirements path as illustrated up and deleting C:\ProgramData\Oracle\Java\javapath;. don't forget to reopen your editor.
