双击启动程序时就出现下面的:
No license was found for feature pwrshell. You have specified the following license location:
Using MGLS_LICENSE_FILE environment variable=C:flexlmlicense.dat
Using MGLS_LICENSE_FILE registry=c:flexlmlicense.dat
Using LM_LICENSE_FILE registry=c:flexlmlicense.dat
Using FLEXlm default locations for license files.

Please see the Mentor Graphics Licensing Quick Reference for help in setting
license locations.

点击确定之后又出现：
Security system wasn't properly initialized: License request for pwrshell feature failed. The program will run in demo mode.

然后就进入demo模式了。
有谁知道这是怎么回事吗？是不是被mentor给查封了？？
