紧急求助 无法安装cadence16.3

求救各位大侠，cadence无法安装啊

按照百度文库里Orcad16.3安装说明进行安装 先安装licence manager后 再安装product installation时出现 server install cannot be carried out inthis workstation as a client installation of SPB16.3 was found here. Installation will not continue. 然后就退出了，之前没看安装教程时，在没安装product installation之前先安装了Client installation 所以出现错误， 求怎么解决，谢谢啊~~ （已经将注册表里有关cadence orcad spb的文件都删除了 都重新卸了再安装也不行）

the client installation is not needed while you try to install spb,after installing licence manager just click product installtaion.others should be ignored.
