vista下安装Patran和nastran

我的是vista系统，安装patan2007R2成功，但是运行是却提示You have requested to run MSC.Patran on a Windows ×××××× There are no version licenses installed to satisfy this request. License File: 27000@a4ef45f157ef4c5 Please request your systems administrator to review the installation procedures for MSC.Software products on your system and/or contact your Support Representative for further assistance
安装过程我看了很多网友的帖子，但是还是失败了
在这请教高手，谢谢！
另外，nastran什么版本可以在vista下安装？
