danpatch · Mar 17, 2020

Hello everyone,

I have a VM server 2012 r2. I am unable to install any CU's, it's been several months now, I tried downloading the update from the MS catalog and installing directly but it still fails.

I was getting error 0x80073701 and in cbs log seeing this line "[HRESULT = 0x80073701 - ERROR_SXS_ASSEMBLY_MISSING]".

I ve uninstalled KB4048958 update that stated problem in cbs log and reinstalled but server result in BSOD critical service failed. By luck i have snapshot and reverted it.

I ve run farbar recovery scan tool. attached is the logs.

Please help.

Hi!

Step#1 - FRST Fix
NOTICE: This script was written specifically for this user, for use on that particular machine. Running this on another machine may cause damage to your operating system
1. Please download Farbar Recovery Scan Tool and save it to your Desktop.
Note: You need to run the 64-bit Version so please ensure you download that one.
2. Download the attached fixlist.txt and save it to the Desktop.
Note. It's important that both files, FRST64 and fixlist.txt are in the same location or the fix will not work (in this case...the desktop).
3. Run FRST64 by Right-Clicking on the file and choosing Run as administrator.
4. Press the Fix button just once and wait. If for some reason the tool needs a restart, please make sure you let the system restart normally. After that let the tool complete its run.
5. When finished FRST64 will generate a log on the Desktop (Fixlog.txt). Please post the contents of it in your reply.

Afterwards, reboot and retry updating again.

3. Please ensure you place a check mark in the Addition.txt check box at the bottom of the form before running (if not already checked).
4. Press Scan button.
5. It will produce a log called FRST.txt in the same directory the tool is run from (which should now be the desktop)
6. Please attach the log back here.

I would recommend that you temporarily uninstall Trend Micro and CA ArcServe.

Hi Sorry for the late reply. Due to security urgent. We have to reformat the server.
Thanks for your help.
