KB3170106 (July 2016 IE11 Security Update) Fails with Error 80073712
The Problem:
The July 2016 Cumulative Security Update for IE11 (KB3170106) Update Fails to Install, giving Error code 80073712. All other updates installed successfully.
AFAIK no malware or other suspicious symptoms, besides a random CHKDSK on boot up a few days / week ago, where it had to repair a tonne of file indexes etc. Could be related, otherwise all seems fine.
Operating System:
Windows 7 Ultimate x64 SP1.
Fully updated besides KB3170106 (This update. Fails) and KBs 2952664, 3021917, 3068708 and 3080149, which I have hidden (Just telemetry crap I believe?).
What I've Tried:
• CHKDSK (Now comes back clean). - Log Attached.
• SFC /Scannow (Detects errors, unable to repair). Also tried this from Safe Mode, and the Repair Mode Command Prompt on my Windows Boot disk, same result. - Log Attached.
• System Update Readiness Tool - (Detects errors, unable to repair) - Log Attached.
• Downloading 2 of the updates that errored in SURT, placed them in Windows\CheckSur\packages directory, which fixed two of the error lines, but still many errors left, as well as errors with the .mum and .cat files of those are updates still present. (This one is strange as one of the updates is KB2952664 which I had hidden and NOT installed..). The log I have attached is from a re-run after this one.
• Downloading the KB3170106 update manually - Still errors. (Said successful once, but obv wasn't).
Resources Available:
• Full Admin access to the problem PC
• A separate Windows 7 Professional x64 SP1 Machine
• Original Windows Install / Boot Disk
From looking at other threads it seems that portions of my Windows Installations have become corrupted, and it will take several runs of the SURT, while adding files to be replaced?
Either ways any assistance is appreciated.
