windows server 升级 oracle 11g opatch包，提示错误Patch location is not valid for apply？

各位大牛好，小弟当前使用的Oracle数据库版本为Oracle 11.2 ，
在升级oracle 11g opatch的时候，提示Patch location is not valid for apply，在此请教各位大神。

下面是具体错误信息。
ZOP-51: The patch location is not valid for apply, because it doesn't have correct metadata, or it points to a patch directory. 
Argument(s) Error... Patch location is not valid for apply
Please check the arguments and try again.
OPatch failed with error code 135
