I run omni rig for my ft 710 and ic7000 (rigs 1 and 2 respectively), wsjtx, fldigi and anything else that works with omni rig is working fine.
in fact i usually have log4om and wsjtx running both connected to omnirig so that if i wanna do phone i dont have to mess around changing cat stuff around.
just installed varac and set to omnirig for cat and PTT control, but i keep getting this error and the ptt test and frequency stuff isnt working.
Any help appreciated.


try running VarAC as admin. maybe its a permission issue related
What is your omnirig version ?
can you attach a screenshot of its settings ?
