ham radio deluxe free trial will not run

So far I like HRD or Ham Radio Deluxe but it seems the older version like 5 no longer work for free. I have been looking and trying some software to see what works with My 746PRO. I want to be able to use some 'Rig Control Software with my Radio. I am a newly recent Ham and I have an Icom IC-746PRO. Of years ago but others here might be of some help. I can't help you with set up on a 746 Pro since I sold mine a couple

Then there's OmniRig, which is free and many like it. I want software that works and I don't want to be a software developers guinea pig. I am willing to purchase a good software if it really works great and is bug free and I guess what I would like to know what all of you are using for rig control software and how much is it. I would like to find a freeware version of software as I, like a lot of people live on a fixed income and any little bit saved helps meet the ends. I did do all the trouble shoot routines and found a CIV Port test utility I installed the utility and was able to communicate with my radio via the manual entry of commands but no Joy on HRD. I tried connecting with the free version of HRD and it will not talk to my radio.
