Cannot start openfire service successfully

when I tried to run openfire.exe, the folling warning is given:

"Error occured during initialization of VM.

Unable to load native library:(I don’t cognize which library it’s because of congarbled code)".

It cannot start openfire service even though I use the command:

open-service /install

open-service /start

openfire version:

java -version: java version “1.6.0_23” jdk1.6.

OS: windowsXP SP3

your help is appreciated.
