Open the Start Menu, type , and navigate to Virus & threat protection .
Wait for the process to hit 100% completion. Windows will automatically replace any missing or corrupted system files. 5. Perform a Clean TeknoParrot Update
Follow these sequential steps to systematically clear out the injection breakdown and get your arcade cabinet software working. 1. Reinstall DirectX Legacy Runtimes
Click the or Check for Updates option to force the launcher to re-verify its folder contents.
