NutsAboutNets, you have a history of not responding to users on this public forum, and your private emails are openly hostile, which is why folks turn to public support forums in the first place. There's no user error here, your app hasnt been updated in ages, and currently does not function properly on the latest iterations of MacOS. Perhaps thats why you've EOLd it. Using sock puppet accounts to claim it does work is duplicitous behavior and likely illegal.
1. The application *opening* doesnt mean it works. It needs to work with the hardware in question, which it does not, and has not for some time now.
2. I installed both the driver you provide with the Touchstone installer package, and when that didnt work, the latest driver directly from Silicon Labs. That driver works fine with other hardware and software, so I know its not an issue on their end, but rather yours.
3. I know nothing about your broken licensing mechanisms, and suggesting I do is absurd. I have only ever installed Touchstone on two computers, and it has been removed from both ages ago. Certainly in the process of attempting to debug your horrendously buggy application I have "installed" it numerous times following clean installs, in attempting to run down how and why any application could be so hilariously incapable of doing what it says on the tin with any degree of consistency.
4. Perhaps if you spent less time arguing with users on the internet, and more time developing stable apps, we wouldnt be having this conversation.
