Eclipse reported “Failed to load JNI shared library"

 I can't open Eclipse because I get an alert that says

Failed to load JNI shared library C:\Program Files (x86)\eclipse\jre\bin\client\jvm.dll

Solution:
First, ensure that your version of Eclipse and JDK match, either both 64-bit or both 32-bit (you can't mix-and-match 32-bit with 64-bit).

Second, the -vm argument in eclipse.ini should point to the java executable. See http://wiki.eclipse.org/Eclipse.ini for examples.
If you're unsure of what version (64-bit or 32-bit) of Eclipse you have installed, you can determine that a few different ways. See How to find out if an installed Eclipse is 32 or 64 bit version?

This is a problem due to the incompatibility of the Java version and the Eclipse version both should be 64 bit if you are using a 64-bit system.

In Windows 7 64 bit you have C:\Program Files and C:\Program Files (x86). You can find Java folders in both of them, but you must add C:\Program Files\Java\jre7\bin to environment variable PATH.
