Hi,

  • Please download SFCFix.exe by niemiro of Sysnative forums, and save this to your Desktop.
  • Download the file, SFCFix.zip, and save this to your Desktop. Ensure that this file is named SFCFix.zip - do not rename it.
  • 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. See illustration image
  • When you see the prompt "Will you allow SFCFix to communicate with Sysnative servers?", type "n" for no. Press Enter to continue.
  • SFCFix will now process the script. It will take some time to complete. Upload the output file SFCFix.txt in your next reply.
  • Restart Windows and attempt to install updates.

    The first time around I didn't get a cmd line to answer N and to hit enter. However, just now I repeated the process and got cmd line plus the attached SFCFix.txt.

    SFCFix.txt

    After following your procedure above file SFCFix.txt wasn't generated on the desktop, but I found a copy in SFCFix.zip, which I have attached. I am currently running the update. Will let you know if successful.
