Thanks for your reply.
Yes, I had viewed the video before upgrade, and stopped the license server.
Sometime, it may take a bit of long time to install or invoke Mentor installer on some of machines. There are multiple MentorGraphcs\install directories on your hard disks,especially you have installed Mentor's Modelsim. I suggest you try to delete all Mentor\install directories on your machine , re-run setup.bat and wait minutes.
