[Solved] Error Could Not Open jvm.cfg
If you are facing the error could not open jvm.cfg then do not worry. It has a simple but weird fix.
I faced the same issue when I tried to run a simple java program. I was using the jdk8. The interesting fact was that the program compiled successfully. But when I was executing the java program then it was giving Error: could not open C:\Program Files\Java\jre8\lib\amd64\jvm.cfg.
In short, below is the scenario
Let’s find out the solution/fix.
Fixed- Error: could not open C:\Program Files\Java\jre8\lib\amd64\jvm.cfg
1. Go to below folder
2. Remove below files from this folder
java.exe,
javaw.exe,
javaws.exe
3. Run the program again, voila, the error is resolved.
2. PATH is not correct
1. Put below the line at the beginning of the PATH.
voila, the error is resolved.
If the above problem still persists, then
3. Remove Oracle directory executable files
Check the below directory
and remove the java related executables.
voila, the error is resolved.
If you are reading this line it means, you are still facing this annoying error. So the last trick is
4. Uninstall Java, Remove references to it from Registry and Reinstall it
JVM: could not open
My friend installed Eclipse with the Blackberry simulator. I’m assuming it was a portable installation because at no point we were prompted to install.
Now, he zipped it up and copied it to my machine when running I receive that error above. Obviously it’s because it’s trying to look for something on my friends directory. How can I change it to my path?
Where do I change this?

I would suggest not running eclipse from a copy of someone else’s installation. This will probably contain lots of installation-specific files which are unlikely to match your machine.
Why not install it yourself, then install the Blackberry Java Developer plugin? It’s available at http://na.blackberry.com/eng/developers/javaappdev/devtools.jsp
Then remove the [BlackBerry simulator version].xml.manifest.bin file.
Now it should be work.
You may also want to check file Settings.rc, found in the folder PATH\plugins\net.rim.ejde.componentpack4.6.1_4.6.1.49\components\bin
first you have a path to your eclipse installation, and then corresponding Simulator you are trying to run.
That should be all.
Though it is not advisable to run a copy of eclipse, there is a very simple way for one to solve such a problem: it is by running the clean.bat file that is in the simulator folder of the specific component pack version folder. The path to that file would look like this: PATH\plugins\net.rim.ejde.componentpack[BlackBerry version]\components\simulator\clean.bat
I think that would do. Still, installing a new version is the best option.
It will be better you install it yourself frsh rather than copying it from friends machine.
But you can give it a try.
Goto your eclipse\plugins\net.rim.ejde.componentpack6.0.0_6.0.0.29 directory and check do on of these files contain this path:
Or else you could grep for problem path in your plugin directory and replace same with updated path.
This error occurse cause your simulator have previously loadded application. Removing them solve your problem.
Quote from Reset and clean the blackberry simulator:
Are you sick of having a million icons on your BlackBerry simulator for every HelloWorld and demo project you have every tested? Try this to remove old programs from the simulator and start with a clean ribbon. From the command line browser to your rim jde directory, switch to the simulator sub directory and run clean.bat. This program takes longer than you would expect (about 30 seconds or so on my 3 ghz machine).
UPDATE Also delete all [app name].cod|cso|debug|jar files from simulator folder Also make sure projects you don’t want on simulator are not active and are not in build configuration.
Java path..Error of 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.

Don’t think if this is a correct way. (perhaps proper installation of Java is a permanent solution). but this is a trick. )
Delete the “java.exe” file from “c:\windows” and “c:\windows\system32″. That should fix it.
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.
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.
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.
is the error coming when i am trying to start eclipse ide.
my C:\Program Files has
what is the problem
i have seen this link but it is not solving my problem can’t find JRE in the JDK

I had similar problem on a Windows machine. I had moved my Java directory from inside «Program Files» (the space in the directory name was giving me trouble) over to c:\
I set all my PATH variables to the new location, restarted the machine and thought that would be enough. Nope
Error: could not open `C:\Program Files\Java\jre1.8.0_66\lib\i386\jvm.cfg
This solution came from the good folks over at coderanch
Start regedit (just type «regedit» into the Run program) and work your way down to HKEY_LOCAL_MACHINE > SOFTWARE > JavaSoft
There you will find several different java directories
Java Development Kit
Java Runtime Environment
In each directory you’ll find different directories for the different version of java (esp. Java Web Start). Open each and every one and you’ll see that your old path is still listed. Double click the Name (left column) of the listing and manually type in the new path.
This problem can show up if you initially install Java in the default location (C:\Program Files) and then later re-install into another location.
The default installation copies java.exe, javaw.exe and javaws.exe to C:\Windows\System32. If you are in this situation and delete these files it will likely solve your issue.
Problem: Eclipse Neon error: «C:\Program Files\Java\jre1.8.0xx.xx\jvm.cfg»
Solution Win7 Pro: System Properties > Enviorment Variables > System Variables > Path > Edit > #make sure the current JAVA directory appears first in the path if more than 1 JAVA directory exist.
In the path that follows, I moved «C:\ProgramData\Oracle\Java\javapath» behind the current directory «C:\Program Files\Java\jdk\bin;C:\Program Files\Java\jre\bin» > save
Path C:\Program Files\Java\jdk\bin;C:\Program Files\Java\jre\bin;C:\apache-maven-3.5.0\bin;C:\ProgramData\Oracle\Java\javapath
I also had this problem and was having trouble finding a solution, but now I did!
If you uninstall your current running jre version and then install higher one you are good to go.
I was using jre1.6 when I had this problem but after installing 1.7 it was solved!
The problem is that your eclipse cant find jre.Just copy and paste your jre folder into eclipse folder and then start eclipse.Delete environment variable.
I recently got the same problem on my Windows 7. The issue was that two different paths were specified for Java in the path environment variable. This can be checked as follows.
On the command prompt, run the following command:
The first one was the cause of the issue and removed it from the path. Eclipse is working now without re-installation.
Note: The environment vars have been as follows always:
What worked for me was to go back to the Java webpage and download the Java jre instead of the jdk, since that is what the stupid computer is now looking for. Then open the C: Program Files>Java and make sure you see jre7 instead of jdk.
Have a simpler solution:
Check your PATH. Most likely it is referring to incorrect java.exe. This started happening to me when I installed OS patch. In process of checkpoint etc, PATH got modified. Once I corrected it (using Environment Variables. ), it worked immediately.
-vm C:\Program Files\Java\jdk1.8.0_121(your JDK version)\bin\javaw.exe
Put it at the top of the file. Most probably it will work.
Sometimes putting javaw.exe in eclipse folder also work (where eclipse.exe is there)
This is an old post, but what solved my solution was editing the `eclispe.ini’ file to include the correct path to the JDK.
Building off of what Lars answered, I did reinstall Java, so that may have been the source of the issue. Reglardless, this is the solution that worked for me. I did not have to delete any files from C:\windows\system32, however. I merely told eclipse to look in the new Java installation directory.
These docs indicated I needed to specify the path to the VM:
I did workaround i.e. changed name of jre folder to the older version e.g. jre1.8.0_191 is after installing update and jre1.8.0_60 was before update. I renamed jre1.8.0_191 with jre1.8.0_60 to solve the issue
I had faced similar problem. Environment variable path problem
JAVA_HOME=C:\Program Files\Java\jdk1.8.0_192
Set the Environment variable after going
Control Panel\All Control Panel Items\System and select Advanced System Settings then set Environment Variables
In System Variables add a new variable JAVA_HOME and variable value = C:\Program Files\Java\jdk1.8.0_192, the path of the jdk file in your system.
and %JAVA_HOME%\bin in the path of the system variables.
Hopefully the problem will solve. After doing this It works fine for me.
Запуск Java дает » ошибка: не удалось открыть `C:Program файлыJavajre6libamd64jvm.cfg’и»
после многих лет работы ОК, я внезапно получаю это сообщение при попытке запустить JVM:
Я попытался удалить и получил сообщение о том, что DLL отсутствует (не указано) Попробовал переустановить, все безрезультатно.
в то же время, при попытке запустить Scala я получаю:
может кто-нибудь помочь?

может быть немного другой причиной, но эта вторая проблема возникает для меня в scala 2.9.0.1 на Win7 (x64), хотя scala-2.9.1.final уже решил этот вопрос, упомянутый здесь:
мой %JAVA_HOME% установите путь следующим образом: c:\program files (x86) \Java\jdk.
обратите внимание на пробелы и скобки.
если вы измените строку 24 в %SCALA_HOME%\bin\scala.bat от:
он работает нормально. Обратите внимание на кавычки параметры команды set, это будет правильно заключать любые пробелы и «специальные» символы (например: пробелы и круглые скобки) в значении переменной.
надеюсь, это поможет кому-то еще искать ответ.
Это работает для меня
Итак, если существует, удалите java.ехе, javaw, который.exe и javaws.исполняемый из System32
поместите %JAVA_HOME%\bin в начале пути.
Если это работало раньше, это означает PATH уже не исправить.
наконец исправлено путем удаления java, удаления всех ссылок на него из реестра, а затем повторной установки.
Я думал, что поделюсь, как я решил ту же проблему «ошибка не удалось открыть lib\amd64\jvm.cfg». Я обнаружил, что во время выполнения Java jre7 отсутствует папка amd64 под lib. Однако у меня есть 1.7.0_25 JDK, который имеет папку jre, а также amd64.
я переместил исходное содержимое папки jre7 в файл резервной копии и скопировал все из 1.7.0_25\jre.
теперь я больше не получаю эту ошибку и могу продолжить работу с scene builder.
установка Java 7 на моем рабочем ПК сломалась после того, как патч был вынужден к нам, давая эту ошибку в любое время, когда вы пытались запустить программу Java. Каким-то образом весь подкаталог » lib » установки Java 7 исчез! Возможно, это было связано с установкой Java 6 и Java 7-в каталоге «jre6» все еще было все.
в любом случае, я исправил его, удалив Java 6 и Java 7 и переустановив только Java 7. Но если файл, на который он жалуется, на самом деле там, тогда у вас, вероятно, есть проблема пути, как описано в некоторых других ответах здесь.
внезапно возникла та же проблема, от одного дня к другому затмение сказало
после попытки запустить java на консоли
Теперь я просто удалил весь каталог
и все снова работало. я не знаю, откуда взялась эта jre, надеюсь, это не вирус
У меня была аналогичная проблема (попытка запустить ведомый агент Дженкинса в Windows) на Windows 2008R2, Java 1.7.0_15. У меня было две ситуации, которые способствовали проблеме, и что изменение обоих из них исправило ее: 1) Установка Java в unix-совместимый путь (изменение от c:\Program файлы. для c:\Software. ); Я не думаю, что это напрямую повлияло на проблему, описанную в этом потоке, но отмечая изменение; 2) Запуск Java не через ярлык. Первоначально это не удалось с помощью ярлыка, но повторный запуск от прямого исполняемый (C:\Software\Java. \bin\java) работал.
переустановка java мне не помогла. Но трюк, чтобы поставить переменную JAVA_HOME в начале env-vars. Проблема возникла после обновления с jdk1.7.0_11-jdk1.7.0_13
другой обходной путь использует shortpath в windows:
это должно работать в среде windows 64, как это работало для меня в win7 64bit версия.
Я изменил путь установки java с c:\Program Files (x86)\java в другую папку, как c:\java\jdk1.7 обновлено %Java_HOME% и значения пути, соответственно,это сработало.
У меня была та же проблема затмение и я исправил это путем изменения JRE от 64 бит до 32 бит:
Окно > Настройки > Java > Установленные JREs > Добавить. > Далее > каталог > выбрать «C:\Program файлы (x86)\Java\jre1.8.0_65 » вместо «C:\Program файлы\Java\jre1.8.0_60»
обычно это из-за обновления JRE.
Это меняет симлинки в\C:\ProgramData\Oracle\Java\javapath
Intall JDK-это исправит это.
