Error running Eclipse: failed to load the JNI shared library

[resolved] error running Eclipse: Failed to load the JNI Shared library

running Android ADT, that is, Eclipse error:

Failed to load the JNI shared library

C:\Program Files (x86)\Java\jre6\bin\client\jvm.dll

where the background is:

1. It has been able to run normally before, that is, it has installed JRE6 normally.

2. JRE6 was later deleted.

3. Just went to reinstall JRE6, the result is still the same error.

4. And has been determined:

C:\Program Files (x86)\Java\jre6\bin\client\jvm.dll



1. Now try to figure out why it still doesn’t work.

do you need to restart the computer??

2. Take a casual look at the current eclipse configuration:




– Dosgi. RequiredJavaVersion = 1.6

is clearly a requirement that Java be version 1.6.

. Reference:

doesn’t feel very helpful.


and make sure that the JDK installed earlier is


is indeed 64-bit. It still doesn’t work.

5. Reinstall


let’s try that.

. 6. There’s definitely a problem with that.

because it says

C:\Program Files (x86)\

means eclipse wants 32-bit Java.

so, again, it looks like we need to find, is it somewhere, the environment variable, or is it this path that’s left in the registry, to delete it and update it to the latest

C:\Program Files\

Java path is ok.

7. Sure enough, in the PATH environment variable, you see that there are two java-related paths:

  • C:\Program Files (x86)\Java\jre6\bin: was added before, estimated to be installed after the jre
  • C:\Program Files\Java\jdk1.6.0\bin: is just installed after the JDK, oneself manually added

, so that’s easy.

to delete the old path:

C:\Program Files (x86)\Java\jre6\bin

turns out to be the same problem.

8. Finally, it turns out that the environment variable is

JAVA_HOME=C:\Program Files (x86)\Java\jre6

so, you never find the corresponding value, now change it to:

JAVA_HOME = C: \ Program Files \ Java \ jdk1.6.0

and, in PATH, we already have:


, that should do it.

to try, and sure enough, you can normally run Eclipse, here ADT:

when running something java-based, here is Eclipse (ADT for developing Android), if it appears:

Failed to load the JNI shared library

C:\Program Files (x86)\Java\jre6\bin\client\jvm.dll

If it’s

or something like that, it’s easy,


  • to see, the corresponding path, whether there is really jvm.dll
    • if not, then obviously, you need to install the corresponding version
      • go to Oracle website to download the corresponding version, JRE or JDK

  • to confirm whether the Java environment variables are normal:
    • JAVA_HOME: this should be the installation path for your JRE or JDK
      • example here, 64-bit win7, installed is the 64-bit JDK 6, so after installation, the corresponding path is:
        C:\Program Files\Java\jdk1.6.0
    • 0

    • 1 PATH: PATH should contain the Java bin directory, similar to
      C:\Program Files (x86)\Java\jre6\bin\
      • hint: but since JAVA_HOME is already set, it can be more commonly written as
  • in addition, hint:

    64-bit (Win7) system, the corresponding software installation directory:

    • 32-bit software, default installation to: C:\Program Files (x86)\
    • 64-bit software, default installation to: C:\Program Files\
