It has come to our attention at there has been a recent explosion of people reporting corruptions with the CNBJ2530.DPB file in Windows 8 and 8.1.
This post aims to outline both how to determine whether your computer is affected and how to repair it should it be. Unfortunately, we have yet to identify the root cause for this corruption at this time but it is part of an ongoing investigation here, and we shall be sharing all of our findings with Microsoft when appropriate to lead, if at all possible, to a final resolution.
First, to confirm whether or not you are affected by a corruption of this file, please perform the following:
Press the Windows Key on your keyboard and X to open up the Power User Tasks Menu
Click (or tap) Command Prompt (admin)
When command prompt opens, copy and paste the following commands into it, press enter after each
sfc /scannow
Wait for this to finish before you continue (approximately 15 minutes)
This program, included as standard with all modern copies of Microsoft Windows, will first scan your system files for corruption and will then provide its analysis in a machine friendly form. We shall therefore be using another program, SFCFix (developed here at Sysnative by niemiro) to interpret this data into a more human friendly format.
Download SFCFix.exe and save this to your Desktop.
Save any open documents and close all open windows.
Double click on SFCFix.exe to open it.
Follow all on screen instructions and upon completion, a file should be created on your Desktop: SFCFix.txt.
This logfile will automatically open. If SFCFix has successfully repaired the corruption, the logfile will contain the following line:
Code:
AutoAnalysis::
FIXED: Performed DISM repair on file Amd64\CNBJ2530.DPB of version 6.3.9600.16384.
The version number will change depending on the version of Windows 8 you are running, but that line signifies that the issue has been successfully repaired. That's it - you're now good to go. If SFCFix reports other corruptions, then please start a thread of your own. Include your CBS folder (per the Windows Update Forum Posting Instructions) and the contents of the SFCFix.txt.
If you are having issues with the automated method, the old manual guide is below:
Read More:
If you see a line that looks similar to the following in your logfile (Not the exact directory name at the moment, just the portions in bold), then you are affected by this corruption. (Note: If you are running a 32bit (x86) computer then amd64_prncacla.inf will be replaced by x86_prncacla.inf)
If the log produces lines that are different to the ones mentioned above, please start a thread of your own. Include your CBS folder (per the Windows Update Forum Posting Instructions) and the contents of the SFCFix.txt.
I will repeat, the line in the log must be exactly the same as the ones mentioned above. If it's similar, do not attempt the fix, and start your own thread.
You may have seen other users uploading a Tekno_Venus folder. That is no longer necessary.
Once you have sourced the files you need, then perform the following steps:
SFCFix Script
Download SFCFix.exe and save this to your Desktop.
Download the necessary file for you corruption, titled 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.
SFC Scan
Press the Windows Key on your keyboard and X to open up the Power User Tasks Menu
Click (or tap) Command Prompt (admin)
When command prompt opens, copy and paste the following commands into it, press enter after each
sfc /scannow
Wait for this to finish before you continue (approximately 15 minutes)
This should repair the corruption. If you would like, you can run SFC once more. It should report back "Windows Resource Protection did not find any integrity violations." If it doesn't, start your own thread.
I will update this thread with new line styles and fixes as I find them, as well as updates to my ongoing investigation into the problem.
If you have any questions regarding this tutorial, let me know. If you are unsure about anything, just ask!
Regards,
Stephen

Re: GUIDE: CNBJ2530.DPB and prncacla.inf Corruptions - Windows 8/8.1
Hey Stephen,
Just to let you know, I have removed the link for 6.3.9600.16384 as the script contains an error. It drops the file in the root folder, not in the .\amd64 folder. Hope you don't mind me editing your post, but I wanted to pull this before anyone else makes the mistake - I just did it on my friend's computer and realised what the issue was :)

However, whenever I run it this is what I get:

I am not an expert user and to be honest this means very little to me but it looks to me as if this is all referring to a different file to the one I am trying to repair. I have downloaded from the dropbox link twice to make sure I have been clicking on the link indicated but this keeps happening. Is the link to the wrong file? Please give me some advice. Thanks.

Re: GUIDE: CNBJ2530.DPB and prncacla.inf Corruptions - Windows 8/8.1
Excellent - many thanks. My problem appears to now be fixed. It's been a real headache for well over a month.
I'm really grateful that you guys have worked out a fix for this problem otherwise this laptop would have been going through a window soon!

Re: GUIDE: CNBJ2530.DPB and prncacla.inf Corruptions - Windows 8/8.1
Hi, I'm sorry to say that the problem that I had which the advice on this thread cured has recurred. In fact it has recurred shortly after each time I have rerun the fix. It is still the problem with C:\WINDOWS\winsxs\amd64_prncacla.inf_31bf3856ad364e35_6.3.9600.16384_none_9590ba64d5b91f79\Amd64\CNBJ2530.DPB
that shows after I run sfc /scannow.
Do you have any further thoughts on this as the laptop is back to where it was before.
Thanks in advance
Re: GUIDE: CNBJ2530.DPB and prncacla.inf Corruptions - Windows 8/8.1
To anyone still experiencing issues with this file, can you start a new thread of your own in the Windows Update forum please and we'll do our best to help you out.
@avo, thank you for taking the time to register and share your experiences with us! So many users cruise through here without even saying thank you to Stephen, but then we get a few like yourself who go above and beyond the call of duty and make it all worth it. We've had fairly high success rates with that dism command, but I think there have been a few cases where it hasn't worked, so Stephen kindly wrote up this tutorial :)
Indeed, the DISM tool can be used to fix this error. However, as Tom said, I have seen cases where it doesn't work, hence this guide.
---
However, since the DISM tool seems to be working often now, I have added it to the tutorial. The guide now has two methods for repairing the corruption, DISM and the SFCFix script. I have also removed the Windows 7 style from performing SFC /Scannow, since the corruptions only affect Windows 8.
Re: GUIDE: CNBJ2530.DPB and prncacla.inf Corruptions - Windows 8/8.1
My particular corrupted file is: C:\WINDOWS\winsxs\amd64_prncacla.inf_31bf3856ad364e35_6.3.9600.16384_none_9590ba64d5b91f79\Amd64\CNBJ2530.DPB. I followed all your guidelines actually twice (yesterday and today) and the file is evidently still corrupted.

Actually Tom it did not fix the corrupted file. I restarted Windows Media Center Scheduler Service and closed Services, I reopened Services and Windows Media Center Scheduler Service had stopped again. I will start a new thread.
Re: GUIDE: CNBJ2530.DPB and prncacla.inf Corruptions - Windows 8/8.1
Thank you so much for the postings here. I had this problem with a corrupted CNBJ2530.DPB and was able to fix it using DISM. Before reading about this problem I had no awareness about DISM or it's capability. Thank you.
You're most welcome!
