使用jacob时，把dll放到window/system32下就成，不需要注册
1、如果出现下面的错误
com.jacob.com.ComFailException: A COM exception has been encountered:
At Invoke of: Version
Description: An unknown COM error has occured.
表示dll的版本不对，换成最新版本即可。
2、如果出现下面的错误
no jacob in java.library.path
java.lang.UnsatisfiedLinkError: no jacob in java.library.path
表示把dll放到path下即可，设置path或是放到window/system32下
