I am trying to setup VARAC fot the first time. I am running windows 10 and a ICOM IC-7300. I have Vara installed and use it on winlink with no problems. I start Vara and then start VarAC.exe and I get the following error. It is keying my radio and have to choose Quit to shut the radio down and then VarAC does not start up. Need some help please. ot sure where to go from here.

I am having a similar issue. I get the same error that you received. Also, after I have closed the program and go back to it, I have to reenter all of my personal and rig information. It seems to work fine while running, just a hastle to reconfigure the VarAC program every time I start it up. I have deleted the files and reinstalled, but the results are the same
