cadence IC5141的library manager打开不了

ade1993

我安装了cadenceIC5141后，打开library manager的时候显示下面错误：
*WARNING* Unable to start up library manager (libManager.exe) after 60 tries.
There maybe an access or network problem.
Start the library manager from an Unix Shell window to test the accessibility.
Variable ddsvMPSTimeOut (60) can be set to increase or decrease the number of attempts.

在论坛上有些人说要改/etc/hosts文件，但是不知道怎么改？有人可以告知下吗？
