    The error code 0xC0000142 (STATUS_DLL_INIT_FAILED) means:

    {DLL Initialization Failed} Initialization of the dynamic link library %hs failed. The process is terminating abnormally.

    We must determine the DLL file causing the problem. Please run a Procmon trace and share the log file on OneDrive or GoFile.io.

    1. Download Process Monitor: http://live.sysinternals.com/procmon.exe
    2. Launch Process Monitor.
    3. Reset the filter options and click OK.
    4. If tracing does not start automatically, press Ctrl+E.
    5. Start an Office app and let it throw the error 0xC0000142.
    6. Now, switch to Process Monitor and stop tracing (Ctrl+E).
    7. Save "All Events" in a PML log file.
    8. Zip the log file and upload it. Zipping it reduces the size by 90%.
    9. Share the zipped file on OneDrive or GoFile.io and post the link here.
