Patran :Your request to run MSC.Patran has been denied. Feature was never checked out

第一次下载Patran，一切按照安装程序安装完成后打开了产生了如题所示的报错：Your request to run MSC.Patran has been denied. Feature was never checked out。在网上查看了一些报错原因后，大概率觉得错误产生在license管理器上。

于是打开MSC.Licensing Utility，首先Stop server，然后Reread licensing file，再Start server。再次打开软件，报错消失。
