Failed to load the JNI shared library on starting Eclipse

This usually happens if you have a 32- vs. 64-bit mismatch between the installed JDK and Eclipse versions!

Your version of Eclipse is trying to access a 32-bit JDK (as indicated by C:\Program Files (x86)), but either fails because Eclipse is expecting a 64-bit JDK or because the 32-bit JDK is missing - consequently you'll need to make sure to match the Eclipse and JDK versions bit wise accordingly.

I had installed both JDK and Eclipse 64-bit versions, but had the same issue...

Finally I discovered that my %PATH% system variable didn't include the folder. Don't forget to change it to the correct folder where your JDK\bin is installed. Worked for me.

-startup
plugins/org.eclipse.equinox.launcher_1.1.1.R36x_v20101122_1400.jar
--launcher.library

use eclipse and os both 64 bit or both 32 bit
