在Windows7 64位系统新安装了Abaqus，启动失败，显示如下：
License server system does not support this feature.
Feature: cae_teaching
License path: 27011devil;
FLEXnet Licensing error:-18,147
For further information, refer to the FLEXnet Licensing documentation,or contact your local Abaqus representative.
Abaqus Error: Abaqus/CAE Kernel exited with an error.
【解决办法】
将X:\Program Files\Dassault Systemes\SimulationServices\V6Rx\win_b64\SMA\site\custom_v6.env文件最后一行 academic=TEACHING 删除，然后重新运行。
提示：若删除后无法保存，提示文件不可修改，可将文件复制到桌面，删除 academic=TEACHING 后，用此文件替换原文件即可。
