Microsoft has changed its offline scanning tool from MSSS-32 to WDO-32 and MSSS-64 to WDO-64. You can see this at

The former Microsoft Standalone System Sweeper (MSSS) BETA is now available and known as the now renamed Windows Defender Offline BETA instead.
Can you replace the files in your next version?
