Fixlet MS15-081: Vulnerabilities in Microsoft Office Could Allow Remote Code Execution - Office 2013 SP1 - KB3054816, modified on 31st December 2020, appears to have an error.
It fails at the expand statement because the statement includes ‘-F:\files\msp’ but the .cab file contains all the content in the root
