I have installed AWR Microwave office successfully. Though I have followed all steps correctly. I am getting following error and have shown in Screenshot.
The error clearly states you do not have a licence for the software. Maybe you have not installed the licence key correctly.
It's many years since I have used Microwave Office, but you need to download the licence key, install it to the correct director and have the dongle plugged in.
There is or was fairly good help on the AWR website, failing that contact AWR for help.
