Error message

this command requires applications to be identified by their exe

What it means

A guard in komorebic's command dispatch: subcommands such as RemoveTitleBar (and other rules targeting specific windows) only accept ApplicationIdentifier::Exe; when the caller supplies a different identifier (e.g. title or class), this error fires because those operations rely on matching process executables.

Solutions

1. Re-run the command with the EXE identifier, e.g. `komorebic remove-title-bar exe <path-to-exe>` instead of a title or class identifier
2. Use `komorebic query windows` or task manager to determine the target process's exe name
