I applied your fix using SFCFix.exe and not via copying the manifest to C:\Windows\CbsTemp\<NUMERIC-DIR>\Windows10.0-KB4517389-x64.cab\. I hope that was correct.
I'm getting another 0x800f081f, logs attached and uploaded.
Alright, done. It seems, that there's something different now: Previously, the progress jumped from 44% to 100% all the time. Now it's taking a lot more time, going through to 73% and then failing with a new error code: 0x800f0988.
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.
Warning: this fix is specific to the user in this thread. No one else should follow these instructions as it may cause more harm than good. If you are after assistance, please start a thread of your own.
Download SFCFix.exe (by niemiro) and save this to your Desktop.
Download the file below, SFCFix.zip, and save this to your Desktop. Ensure that this file is named SFCFix.zip - do not rename it.
Save any open documents and close all open windows.
On your Desktop, you should see two files: SFCFix.exe and SFCFix.zip.
Drag the file SFCFix.zip onto the file SFCFix.exe and release it.
SFCFix will now process the script.
Upon completion, a file should be created on your Desktop: SFCFix.txt.
Copy (Ctrl+C) and Paste (Ctrl+V) the contents of this file into your next post for me to analyse please - put [CODE][/CODE] tags around the log to break up the text.
