Moxtell Tonfotos installation is pretty simple. It only stores its files in one place (AppData/Local/tonfotos) and its database and configuration in another (AppData/Roaming/tonfotos), so you don’t need any external software to uninstall Tonfotos cleanly, it does not put any dll’s into Win32 and so on. It does not leave garbage in registry. I would actually not recomend using any software like that to remove Tonfotos, since I have no idea what they do and if they introduce any additional damage into your system.
Some users have reproted that recognition instability issues when CUDA is installed, but it never resulted in frezes, only in missing faces. And, as I understand, in your case you don’t have CUDA runtime installed, so it cannot be the source of the issue.
Actually, I am running out of ideas what can be wrong, especially because it all worked fine before.
By the way, have you already tried my suggestion with renaming people.tnfp
? This would make this message box not to appear. You said “Did work either” but as I can see from the logs, message box actually pops up. What message box is that? Could it be that you have ’people.tnfp` in multiple places? Actually you don’t need many, it is enough to keep one, they are identical.
