SPAPI_E_DEVICE_INSTALLER_NOT_READY
SPAPI_E_DEVICE_INSTALLER_NOT_READY (0x800F0246) is a Windows SetupAPI driver-installation error. This code means one of the installers in the device-installation path is not ready to run. A previous install, a pending restart, a service state, or device re-enumeration can prevent the next operation from starting.
What to check
- Check for another active driver installation or Windows Update operation.
- Review the SetupAPI log for the installer that reported it was not ready.
- Restart only when the log or installer state indicates a pending reboot or unfinished device transition.
