Delete the “java.exe” file from “c:\windows” and “c:\windows\system32″. That should fix it.

In case you get here and scroll this far down, the newer Oracle versions of Java x86 and probably also x64 are horribly broken. You may find that after removing all versions of Java, and even manually deleting all the versions you find in c:/program files/ and c:/program files (x86)/ that you still can’t properly run a fresh install of Java.
I’m here to tell you why, and how to fix it.
Go to C:\Program Files\Common Files\ and DELETE the Oracle directory. It has a version of Java underneath it inside a junction (symlink) that is sequestered away from all your other installs. Bastards.
Now, also go to System Properties -> Advanced -> Environment Variables and edit the PATH under System Variables. Find the place where the Oracle folder is referenced, and delete it. Close all your windows down, reboot to be extra sure if you want.
Install the JRE or JDK. Open a command prompt and type ‘java’ and if it comes up, you’re golden. If not, go back to the PATH variable and add «C:\Program Files (x86)\Java\jdk1.8.0_221\bin» or whatever looks right for your machine.

this should be an internal file of JRE and in general you shouldn’t deal with it when you’re running/compiling java.
Here you can find an explanation of what exactly this file is intended for.
Bottom line, your Java installation is somehow corrupted, so as a first resort to resolve this issue, I suggest you to re-install jre.
You should ensure that you’re installing the right jre for your architecture.
Hope, this helps

You can not Uninstall/Reinstall JRE if you are having this error.
That’s why because previous installation has copied 3 files namely Java.exe, Javaw.exe, javaws.exe in the c:/windows/system32 folder.
Simply go there and remove these files and download a fresh version of jre from oracle and install it. I will prefer JDK 1.6 update 45. Which is very stable.

Java mysteriously broke on my work PC after a security patch was pushed out to us, giving this error whenever you tried to run a Java program. Somehow the ‘lib’ subdirectory of the Java 7 install had vanished! It might have been related to having multiple Java versions installed simultaneously.
If you’re getting this error there are basically two things that could be wrong:
1) Your Java installation is broken. If the file/directory it’s complaining about doesn’t exist, uninstall and reinstall the JRE and then it should be there. This fixed it for me.
2) If the files are there, your PATH is somehow incorrect or pointing at an old/broken Java install. In this case you either need to fix your PATH to point to the correct java.exe/javaw.exe, or use a fully qualified path. So instead of:
java <whatever>
Use
c:\<full path to correct JRE>\bin\java.exe <whatever>
3) If your PATH is correct and files are there and it’s still failing, the path could be getting truncated because it is too long. see: Running Java gives «Error: could not open `C:\Program Files\Java\jre6\lib\amd64\jvm.cfg'» .

i also had the same issue due to one more instance of java,javaw and javaws in C:\Windows\System32 which was pointing to jre6 and my default location of jre was pointing to this(C:\Windows\System32) location. Even having jdk 1.8 as my JAVA_HOME location i were getting this problem.
so either remove or rename java,javaw and javaws it will work.

If you have installer deployed Java on Windows and decided to bring some order to your JDKs with folders moving…
All answers with java.exe in Windows\System32 are right but in more tough situation — there are no files, but error messages still happen, then remember about Windows Registry entries (look regedit.exe).
They store information about JRE folder in this registry key:
win32:
HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment
win64:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\JavaSoft\Java Runtime Environment

The program can be compiled but while running it leads to such an error:
Could not open C:\Program Files\Java\jre6\lib\amd64\jvm.cfg
It indicates that the jvm.cfg file is missing in Program files. Reasons may be file corruption or file may be deleted. Install JRE again in «Program Files» folder.
Another case which happened with me is that I installed 32 bit jdk & jre in my 64 bit system in Program Files(x86) and my Program Files folder was empty. That was the reason for that error. So I installed 64 bit JRE in Program Files folder and it started to work. Note that it is not related to jdk version. Associated with only JRE problem.

I was getting the same error with my docear program on windows 7.
What I found is that I had two instances of java 1.6 installed on my computer. One instance has a jvm.cfg and the other does not.
Modifying my path to search the correct instance of java (in bold) first fixed the problem.
Here is my corrected path:

Java загадочно сломалась на моем рабочем ПК после того, как исправление безопасности было вытолкнуто нам, давая эту ошибку всякий раз, когда вы пытались запустить Java-программу. Так или иначе, подкаталог «lib» установки Java 7 исчез! Возможно, это связано с тем, что одновременно установлено несколько версий Java.
Если вы получаете эту ошибку, есть две вещи, которые могут быть неправильными:
1) Ваша установка Java нарушена. Если файл/каталог, на который он жалуется, не существует, удалите и переустановите JRE, а затем он должен быть там. Это исправило это для меня.
2) Если файлы есть, ваш PATH каким-то образом неверен или указывает на старую/сломанную установку Java. В этом случае вам нужно либо исправить свой PATH, чтобы указать на правильный файл java.exe/javaw.exe, либо использовать полный путь. Поэтому вместо:
java <whatever>
Использование
c:\<full path to correct JRE>\bin\java.exe <whatever>
3) Если ваш PATH правильный, и файлы там, и он все еще не работает, путь может быть усечен, потому что он слишком длинный. см.: Запуск Java дает» Ошибка: не удалось открыть `C:\Program Files\Java\jre6\lib\amd64\jvm.cfg ‘».
Can anyone please tell me why I get the following error when I try to run my Java programs? The programs get compiled successfully but are not able to be run. I have already set the path of Java.

В программировании, что-то может пошло не так. Часто, даже если вы успешно написали свою программу, необходимо будет научиться ее запускать. В этой статье мы рассмотрим одну из самых распространенных проблем, связанных с запуском Java-файлов — Error: could not open `…\jvm.cfg’.
Первым шагом в решении этой проблемы является понимание, что такое jvm.cfg. Файл jvm.cfg — это файл конфигурации Java Virtual Machine (JVM), который определяет, какая версия JVM будет использоваться при запуске программы.
Обычно файл jvm.cfg находится в папке \lib\amd64 (или \lib\i386, если у вас 32-разрядная операционная система), которая находится в установочной папке Java. Если этого файла не существует, или если он находится в неправильном месте, то при запуске Java-программы вы можете столкнуться с ошибкой «could not open `…\jvm.cfg'».
Существует несколько способов решить эту проблему:
1. Проверьте, установлена ли JDK
Первым шагом является установка Java Development Kit (JDK). JDK — это пакет, который содержит все необходимые файлы для разработки и запуска Java-программ. Если вы не установили JDK, то необходимо загрузить и установить его с официального сайта.
2. Проверьте путь к jvm.cfg
Если файл jvm.cfg существует, но находится в неправильной папке, вы должны перенести его в правильное место. Убедитесь, что файл jvm.cfg находится в папке \lib\amd64 (или \lib\i386, если у вас 32-разрядная операционная система), которая находится в установочной папке Java.
3. Проверьте переменную PATH
Еще одной причиной, по которой вы можете столкнуться с ошибкой «could not open `…\jvm.cfg'» является то, что переменная PATH не установлена правильно. Переменная PATH — это список путей к папкам, в которых операционная система ищет исполняемые файлы.
Чтобы исправить эту ошибку, вы можете добавить путь к установочной папке Java в переменную PATH. Чтобы это сделать, следуйте этим инструкциям:
1. Откройте меню «Пуск», нажмите правой кнопкой мыши на «Компьютер» и выберите «Свойства».
2. В левой части окна нажмите на «Дополнительные параметры системы».
3. В открывшемся окне выберите вкладку «Дополнительно».
4. На вкладке «Переменные среды» найдите переменную PATH и нажмите «Изменить».
5. Добавьте путь к установочной папке Java в конец строки, разделенный точкой с запятой. Например:
C:\Program Files\Java\jdk1.8.0_221\bin;
6. Нажмите «ОК» во всех открытых окнах.
4. Проверьте версию Java
Если выполненные мероприятия не помогли решить проблему, она может быть связана с тем, что программа использует другую версию JVM, чем та, которая у вас установлена на компьютере. Чтобы проверить версию Java, установленную на компьютере, выполните эти действия:
1. Откройте командную строку (нажмите клавишу Win + R, введите cmd и нажмите Enter).
2. В командной строке введите команду: java -version
3. Нажмите Enter.
Информация о версии Java будет выведена в командной строке. Если программа, которую вы пытаетесь запустить, использует другую версию Java, чем та, которая у вас установлена, то вам необходимо установить правильную версию Java.
В заключение, если вы столкнулись с ошибкой «could not open `…\jvm.cfg'», это может быть связано с несколькими причинами. Убедитесь, что JDK установлен правильно, переместите файл jvm.cfg в правильную папку, проверьте переменную PATH и убедитесь, что программа, которую вы пытаетесь запустить, использует правильную версию JVM. Если вы все еще не можете запустить свою программу, обратитесь за помощью к специалистам. Но преимущественно, проблема может быть решена самостоятельно, используя инструкции выше. Счастливого программирования!
