Asetek RaceHub crash or stale-process recovery

A confirmed Asetek RaceHub application fault or leftover process can justify a controlled restart. First separate an app failure from a device, driver, or firmware issue.

Checks and expected results

Before you repair it

  • RaceHub 4.5.1 (September 24, 2026) fixes input stopping after rotary movement, missing LMU TC/ABS and EVO DRS data. Match the symptom and installed version, then update manually and retest.
  • Close every supported simulator and save any work in the companion app.
  • Identify the installed RaceHub app and its known helper; review any prompt needed to close the elevated helper.
  • Do not restart device software during firmware flashing or while an update’s completion is uncertain.
  • Check the installed executable location before relaunching; retain the exact crash time and message if the app fails again.

How to confirm the result

Asetek RaceHub should relaunch from its validated installed location and remain running. Check device visibility and expected controls before entering a session. If the app closes again, preserve the new error for vendor support.

Repair limits and when to stop

This recovery does not flash firmware, replace drivers, recalibrate devices, or remove wheel profiles. Remaining open for the verification interval does not prove long-term stability or solve every device-detection issue.

How PitMedic recognizes it

Built-in response

RaceHub 4.5.1 (September 24, 2026) fixes steering-wheel input stopping after a rotary is turned, missing LMU TC/ABS data and EVO DRS data. Compare your version and exact symptom, follow Asetek's supported update manually, then retest the control or display. PitMedic closes the RaceHub app and its known elevated helper, relaunches the validated installed app, and verifies that it stays running.
