想求助一下:win7 64位的电脑,已经安装了envi4.8,可用。现在想安装envi5.0。先是运行了安装程序,然后导入了证书,覆盖了idl,但还是提示说cannot connect to license server system.the license server managee(lmgrd) has not been started yet, the wrong port@hoost or license file is being used, or the port or hostname in the license file has been changed.请问应该如何解决?
