If Java doesn't work, make sure the following is true: On Windows: Copy the NPOJI610.DLL from C:\JDK*\jre\bin to "\plugins" directory of your installation.
If you install the JRE, the path would be C:\Program
Files\JavaSoft\jre\bin\ ('JavaSoft' may be two words); installing the
J2SDK gives a path of C:\j2sdk*\jre\bin\ . . . and the necessary .dll.
NPOJI600.dll doesn't do the trick, I'm afraid. At least it didn't for me.
