Installing the DAT via the programs section did work, my 4th MID package I created with VSE 8.8 Patch 1 baseline (VSE880LMLRP1) + VSE880P2 (Patch2.msp) + epo5600eng does appear to paritally work.
Per KB51111 I added these 4 hotfixes in the MID program section in order per footnote 6
HF01=805660 VSE88HF805660.exe /silent
HF02=778101 VSE88HF778101.exe /silent
HF03=820636 VSE88HF820636.exe /silent
HF04=846582 VSE88HF846582.exe /silent
June 13th DAT package (7105xdat.exe) VSECURDAT.exe /SILENT
however the resulting installation only has Hotfix_820636 present in the registry (HKey_Local_Machine\Software\Wow6432Node\McAfee\DesktopProtection). When I manually verify the file versions installed on the computer most are version 126.96.36.1996 (patch 2 versions?) that should be newer with the updated files included with HF01=805660 ver 188.8.131.528 and HF02=778101 ver 184.108.40.2066. Any suggestions on how to troubleshoot the missing hotfixes?
