Error 4 with “exclusive” is rarely a game-breaking bug in TeknoParrot itself. In 90% of cases, it’s caused by Windows security software blocking the exclusive fullscreen hook or missing runtimes . Disabling antivirus temporarily (just to test) and switching to borderless fullscreen are the fastest diagnostics.

If the error started after an update, your configuration files might be corrupted:

Visit the official TeknoParrot Discord server—upload your error log (found in Logs\TeknoParrot_log.txt ) and mention "Error 4 Exclusive." The community devs are responsive and will pinpoint the exact driver conflict.
