[SOLVED] KB3000850 failing to install windows 8.1

Brown · Mar 19, 2015

Hi All,

Microsoft update KB3000850 is refusing to install on my Windows 8.1 Pro PC. All other updates are installed fine.

I've tried using windows update, and also manually downloading the update from MS and installing standalone. It always fails on 8% installed whilst rebooting, and then rolls back changes.

I've done SFC/SCANNOW, this finds issues every time but says it cannot solve them.

Any help much appreciated.

Thanks

Appreciate the help

Thanks. Do you have a Kodak printer by chance?

Brown · Mar 25, 2015

Yes I do, Kodak Hero 5.1.

Is that the source of the problem somehow?

Thanks

BrianDrab · Mar 25, 2015

Yes I believe so and I think I have a fix for you. I have to finish a generator test at work and then I'll post the fix.

BrianDrab · Mar 25, 2015

Before providing a fix we need to take a look on your system for some files to validate my suspicion. Please do the following.

Step#1 - Verify Files
1. Save the attached SFCFix.txt file to your desktop.
2. Drag the SFCFix.txt file and drop it on top of SFCFix.exe and then let go of the mouse.
3. The process will run and notepad will open when complete.
4. Please paste the contents of this in your next post.

Thank you.

Hi again,

Done as per instructions, see:

Thanks

Cool, confirmed. You are missing two directories. We can re-create them but I need a log first. Please zip up and attach the following log.

C:\windows\inf\setupapi.dev.log

OK. Here's the fix. Are you comfortable creating folders and copying files? If so please do the following. If you aren't comfortable doing this please let me know and I'll provide a more automated way to do this.

Create the following two directories. Copy and paste the folder names so it's exact.

C:\Windows\System32\DriverStore\FileRepository\wiaek002.inf_amd64_5b5a15ef9a58384c\
C:\Windows\System32\DriverStore\FileRepository\prnekcl2.inf_amd64_5d5f2ed31b4e4a9b\

Copy wiaek002.inf from C:\Windows\Inf and paste into the 1st folder you created above.
Copy prnekcl2.inf from C:\Windows\Inf and paste into the 2nd folder you created above.

Then you should be able to install this update. It may take a little while to install but shouldn't fail. Please let me know. Thanks.

Hi again,

I created the structure as described, see attached image.

Once done I rebooted then ran the standalone installer for the update. It took almost 2 hours to run through, and considering I have an i7, 8GB RAM and the O/S is on an SSD, I was surprised it took that long. Still, had no errors and when complete rebooted. Unfortunately it got to 8% again and failed, saying it had to revert changes.

I tried from windows update too and that also took forever and failed in the same way.

Update KB3048778 is also queued to update now (optional update) but I've not done it yet as I don't want to change anything.

Any help much appreciated, I'll post anymore logs you need

Cheers

BrianDrab · Mar 27, 2015

Interesting. Can you zip up and attach the following two folders?

C:\windows\Logs\CBS
C:\windows\Logs\DISM

Thank you.

Brown · Mar 27, 2015

CBS and DISM zip:

Thanks

BrianDrab · Mar 27, 2015

Thanks for the info. I'd like to try the following. The directory names are slightly different. When attempting the install, do it manually from the one you downloaded instead of through Windows Update. Let me know how it goes.

C:\Windows\System32\DriverStore\FileRepository\wiaek002.inf_amd64_57f9361b96ceea4b
C:\Windows\System32\DriverStore\FileRepository\prnekcl2.inf_amd64_59438dc7ce792b20

Copy wiaek002.inf from C:\Windows\Inf and paste into the 1st folder you created above.
Copy prnekcl2.inf from C:\Windows\Inf and paste into the 2nd folder you created above.

Brown · Mar 28, 2015

Nailed it.

Created the file structure as stated, see picture.

Ran standalone installer, took about 90 seconds, rebooted and installed without issue.

Thanks for your help with this one, I would never have sorted it myself.

Are you able to explain how what you suggested fixed it?

Cheers

BrianDrab · Mar 28, 2015

Honestly I got lucky. Everything was showing clean in your logs but obviously something was amiss. I found this fairly long post where they stumbled upon this solution. Your logs didn't show the issues that they were having though so it was very lucky and a hunch. I'm just glad it worked. To keep things clean and avoid issues you may want to remove the following two directories (our first attempt) which didn't work.

C:\Windows\System32\DriverStore\FileRepository\wiaek002.inf_amd64_5b5a15ef9a58384c
C:\Windows\System32\DriverStore\FileRepository\prnekcl2.inf_amd64_5d5f2ed31b4e4a9b

Other than that I'm very happy we were able to assist you with this.

Brown · Mar 29, 2015

Directories removed.

Just read that post too, seems Kodak is involved somehow. Good spot, I think I looked at that post before I submitted a request to this forum but gave up reading before I got to the end.

Thanks a lot for your help, great effort.
