One of the most common and frustrating errors is variations of or messages indicating that keys could not be found at the "top" of the program's initialization phase.
%USERPROFILE%\.switch\prod.keys (e.g., C:\Users\YourName\.switch\prod.keys ). Linux/macOS: $HOME/.switch/prod.keys . hactool prodkeys does not exist top
(Replace somefile.nca with any valid Switch NCA file.) One of the most common and frustrating errors
If hactool cannot find the keys in the default location, you can explicitly tell it where to find them using the --keyset command. Use this command structure: hactool prodkeys does not exist top
