Running Java gives Error could not open C Program Files Java jre6 lib amd64 jvm cfg

Question

After years of working OK  I m suddenly getting this message when trying to start the JVM   Error  could not open  C  Program Files Java jre6 lib amd64 jvm cfg    I tried uninstalling  and got a message saying a DLL was missing  unspecified  Tried re-installing  all to no avail   At the same time  when trying to start Scala I get    Java jdk1 6 0 25 bin java exe was unexpected at this time    Checked  JAVA HOME  and  path  - both OK  Can anyone help

Another workaround is using shortpath in windows:

open windows command console using cmd.exe
goto c:\
type command> dir program* /x
it should display as short path like: PROGRA~2
so C:\PROGRA~2 is same as C:\Program Files (x86)
in your JAVA_HOME replace path to : C:\PROGRA~2\Java\jre7

This should work in windows 64 environment as it worked for me in win7 64bit version.

Error  could not open  C  Program Files Java jre6 lib amd64 jvm cfg    Looking   it the issue of post install script is there and getting propagated since I am using update jdk8 1 8 0 191 since issue occurred with me after installing update of java and which was happened automatically    Error  could not open  C  Program Files Java jre1 8 0 191 lib amd64 jvm cfg    This will be never ending in this case and need to do workaround like changing path s manually

I checked my environment variables - JAVA HOME  amp  PATH and they all refer to C  java  So this was bit frustrating  After sometime I found that the default installation also copied java exe  javaw exe and javaws exe to C  Windows System32  i e  uninstall of JRE didn t go well   I just removed them and voila  I m back on track  That annoying error is no longer popping   This works for me  So  If exists  remove java exe  javaw exe and javaws exe from System32

I had the same problem in Eclipse and I fixed it by changing the JRE from 64 bit to 32 bit   Window   Preferences   Java   Installed JREs   Add      Next   Directory   select  C  Program Files  x86  Java jre1 8 0 65  instead of  C  Program Files Java jre1 8 0 60

I had a similar problem  trying to start a Jenkins slave agent on Windows  on Windows 2008R2  Java 1 7 0 15 I had two situations that contributed to the problem and that changing both of them fixed it   1  Installing Java in a unix-compatible path  changing from c  Program Files     to c  Software       I don t think this directly affected the problem described in this thread  but noting the change   2  Running Java not through a shortcut  It originally failed with a shortcut  but re-running from the direct executable  C  Software Java    bin java  worked

I thought I will share how I resolved the same issue  Error Could not open lib amd64 jvm cfg   I found the Java run time Jre7 is missing amd64 folder under lib  However  I have 1 7 0 25 JDK which is having jre folder and also having amd64   I moved the original contents of jre7 folder to a backup file and copied everything from 1 7 0 25 jre   Now I am not getting this error anymore and able to proceed with scene builder

I had this problem after updating your java  The best way to solve this problem is just go to your c  ProgramFiles Java folder  There you will find two jre folders one is as jre your version and other with exactly like jdk folder  Try to remove jre 1 your version folder  There you go your problem is solved  Hope this might help  It s worked for me

The Java 7 install on my work PC broke after a patch was forced out to us  giving this error any time you tried to run a Java program   Somehow the entire  lib  subdirectory of the Java 7 install vanished   Might have been related to having both Java 6 and Java 7 installed -- the  jre6  directory still had everything there   In any case  I fixed it by uninstalling both Java 6 and Java 7 and reinstalling just Java 7   But if the file it s complaining about is actually there  then you re likely having a path issue as described in some of the other answers here

User · Answer

If this was working before  it means the PATH isn t correct anymore   That can happen when the PATH becomes too long and gets truncated  All posts  like this one  suggest updating the PATH  which you can test first in a separate DOS session  by setting a minimal path and see if java works again there     Finally the OP Highland Mark concludes      Finally fixed by uninstalling java  removing all references to it from the registry  and then re-installing     scary

C  ProgramData Oracle Java javapath   I took a back up of the files in it and removed those files from there  Then I opened a new cmd prompt and it works like a charm

Might be a slightly different cause  but that second issue occurs for me in scala 2 9 0 1 on Win7  x64   though scala-2 9 1 final has already resolved this issue mentioned here    Java jdk1 6 0 25 bin java exe was unexpected at this time    My  JAVA HOME  set to a path like this  c  program files x86  Java jdk     Note the space and the parentheses   If you change line 24 in  SCALA HOME  bin scala bat from   if exist   JAVA HOME  bin java exe  set  JAVACMD  JAVA HOME  bin java exe   to  if exist   JAVA HOME  bin java exe  set   JAVACMD  JAVA HOME  bin java exe    It works fine  Note the quotes around the set command parameters  this will properly enclose any spaces and  special  characters  eg  spaces and parentheses  in the variable s value   Hope this helps someone else searching for an answer

I had a slight different solution to this problem  my PATH and JAVA HOME were pointing to JDK12 in   C  Program Files Java   but execution of the command    Java -version   gave the error   Error  could not open  C  ProgramFiles Java jre1 8 0 212 lib amd64 jvm cfg    I had to delete a folder of executables  Java exe  javaw exe etc   in a different directory than System32  as other answers here and blog posts have suggested  Instead I found the problem lied with executables found in   C  Program Files Common Files Oracle    as there was nothing Java related in   C  Windows System32   If you re having this issue and nothing is in System32  check this  common files  directory mentioned above for an oracle directory and delete it    After  your PATH references should work fine
