Symptom:
Error 1720 “LoadDefaultShowFile script error” (Windows 10 only)
Cause:
COM+ Windows System is not running due to Realtek/Dolby sound driver startup issue.
This is a critical part of Windows that ONYX utilizes for real time synchronization across the software. The issue may be resolved by Dolby in a newer driver at some time. We created a workaround.
Confirm by launching “Component Services” from the Start Menu
Open Computers/My Computer. A Red Arrow will show next to the monitor icon.
Selecting COM+ Applications results in Error code 8004E00F
Fix :
Change the DOLBYDAXAPI service to delayed Start.
Apply this registry file to the PC and reboot.

- Hide Dolby – Extension updates (https://answers.microsoft.com/en-us/windows/forum/all/error-code-8004e00f-com-was-unable-to-talk-to-the/f32b5cd3-e502-4bd0-a305-3b3029430ec0)
- Disable services Lenovo Hotkey Client Loader, Lenovo Intelliigent Thermal Solution Service, Lenovo Platform Service, Lenovo Smart Standby
Install ONYX only if the COM+ error is solved.
