SUMMARY "%APPDATA%\Local\kritarc" is wrong. (from FAQ Where are the configuration files stored?) Where are the configuration files stored? Windows %APPDATA%\Local\kritarc This is wrong. %LOCALAPPDATA%\kritarc This is correct.
I've tested this under a zero configured Windows 10 21H2. There is no such folder as "%APPDATA%\Local\" on my system. I can confirm that "%LOCALAPPDATA%\kritarc" led to the correct file. I will make an MR to Krita documentation website.
