I have two family relatives. One owns the Linx hearing aids, which are supported by Aventa 3.7 or above. The other relative owns CS62W aids which are supported by Aventa 3.5
I tried to install both versions but they conflict and stop me from proceeding to fitting steps.
Could you please give me some advice on this case?
What happens if you create a 2nd user account on your computer and install one version of the software exclusive to each user? Or otherwise just use two computers, one version to a computer. Perhaps if nothing else works, it would pay to get a used computer just to install one version of the software?
