Problem with launching HP HFSS software

I am a beginner of HP HFSS user. After download a HPHFSS software and tried to use it. I always have an error message

HP HFSS Error Aborting
! Exception: Give a debugger a shot at it
Yes No

If I click Yes:
Program Error hfss.exe has generated error and will be closed by window. You will need to restart the program.
An error log is being created.

And HP HFSS will be closed in either I click YES or NO

Many Thanks for your help

I wonder if you have an obsolete version of the HFSS code. At one time both HP and Ansoft were selling it.

You might contact Ansoft for help and the latest software. It isn't exactly inexpensive.
