B.Net Update = Exception Processing Message and File I/O Error

Support Technical Support
1

I keep getting the following error:

“Windows - No Disk”
(X) Exception Processing Message 0xc0000013 - Unexpected parameters

I cannot log in even though I had no problem a few minutes earlier. Some help would be appreciated this is getting annoying as it will not go away.

Windows - No Disk

Cancel, Try Again and Skip.

Click any of them and it pops up again, and again and again.

Background Information:

Edison in their usual bungling incompetence and inability to provide power reliably decided to flash the power on and off twice today, but I have a emergency power-pack set up to protect the computer from their antics after they fried my last one 8 years ago with the same crap.

For some reason the second time they flashed the power on and off my PC was shut down and the emergency Power did not work that time. While I am not sure what is going on but I tried reinstalling B.Net as this is the ONLY app messing up like this.

Mind you however, I seriously doubt the power outtage was the issue, because this exact same error also happened also one time when Blizzard forced the Battle.Net update through earlier today. It was not as antagonistic or troublesome to open however as a single “Try Again” was enough to dismiss the error then. This was before the power outage occurred.

Following a reinstall the error still happens. I am being prompted to put my pass-word in now. I will do so, but I want Blizzard to keep an eye on things as for a moment I saw THREE Battle-nets running at the same time. A part of me wonders if this isn’t some sort of janky new virus, though the other half of me wonders how I could of gotten such a thing since I only use this PC to play WoW.

Update:

Putting my login info in, Battle.net tries to connect and then I get the same BS error code again. This has to be something Blizzard did in today’s update. Everything else is working except Battle.net.

Task Manager shows I have 5 different Battle.Nets running now. 3 Have the Battle.net Logo. One is slightly different, and then a final one called Blizzard Update Agent shows the Icon [Blizz]. What the hell is going on here?

Would love to try and log in to the game, but apparently SMS Protect isn’t enough to let me bypass the Authenticator (which is dead, and which Blizzard no longer sells). The game works fine however and I was able to make it to the login-screen. This further reinforces my thoughts that it is NOT a issue on my PC’s end, and rather Blizzard’s end.

I am convinced this is not my PC’s fault now. After several attempts I was able to get back on B.Net and now magically everything is working, though Battle.net is begging to let me update ‘everything’ which I am suspending while I check my account out.

For how long this scenario will last, I have no idea but clearly something popped on Blizzard’s end in their update. Battle.net’s app upon a fresh install has a blank sheet icon instead of the usual working icon.

What convinces me that this is on Blizzard’s end is the fact that a faulty PC does not magically fix itself suddenly.

Now doing a log out from the game and B.Net to see if the issue is fixed.

Issue remains.

I have conducted all Windows Updates and am looking through my Drivers, but I see no issues on my side as of yet. Some form of dialogue with someone in Blizzard Tech who can assist would be greatly appreciated.

I suspect I could log into the game if I ignored B.Net entirely as it is that app and that app alone making this issue, but as before you do not allow SMS to serve as the authenticator I am unable to go further. You do not sell the Authenticator now and I am unsure how wise it is to remove my Authenticator in this scenario or how secure the mobile ones are.

Further Data:

As a few final side notes, if I uninstall Battle.Net and then reinstall it, then I only get 1 of the Exception Processing Messages. Upon putting in my Password and logging in, Battle.net ‘does’ work, albiet only the first load.

Subsequent loads cause the same infinitely repeating error message to come up. However I was able to break this load-cycle when I forced B.net to stop and shut down Agent.exe with the Task Manager, and then did a reload. At that point it went through without a single problem, which is the first time that has happened tonight.

So… yeah.

Fought for another 20 minutes to get B.Net to load, forced everything to shut down again. And then magically the second time I booted it, it works perfectly.

Might be nothing, but I’ll mention it for side-related data. I won’t deny that it is a little eyebrow raising to see “two” Battle-net icons open in the Notification Icon Area. Especially when the second Icon immediately vanishes the second I open it, as if something is trying to hide itself.

Could it be that Battle.net is trying to open multiple copies of itself? I have no idea as I don’t know how you guys have it set up. I just know it’s been screwing up ever since the update. I sure hope you patch this and fix it in the downloadable B.net you have on your website.

I say that only because if this matter persists, I certainly won’t be allowing B.net to conduct any client updates aside from the ones required to play the games, going forward if this is what I have to look forward to. I’ve run 20 AV scans and my PC comes back as clean, so no it’s not a virus.

One last thing to add to this report. Initially I thought that perhaps there was some sort of corruption in the drive B.net was in. However upon installing it in my SSD external Drive where WoW is located, the same error manifested. I uninstalled the B.Net app (but not my Warcraft Game), and reinstalled it.

Across multiple installs and seemingly irrespective of which disk I install it on, the error crops up. My Operating System is Windows 8.1. I also tested Diablo III and Heroes of the Storm, which are on my HDD, and both ran without any issue.

Factoring in that FFXIV functions, The Old Republic Functions and literally every other game I have on Steam or otherwise functions without any problems, I can only assume that the Battle.net App, and the update from yesterday and today is the common thread causing all of these problems.

Please advise.

Update: 09-03-20

Issue still occurs. Battle.net varies between working after 1-2 tries with the error, and going into a perpetual error message that no matter how many times I click “Try Again” or “Continue” the same pop up comes back.

“Windows - No Disk”
(X) Exception Processing Message 0xc0000013 - Unexpected parameters

Would someone please explain what exactly this error is saying to me? I’d love to know what it means and I seriously doubt I have a virus since Webroot and Norton both are saying my system is clean.

You know, I sure wish someone from Tech Support could at least ‘tell’ me why B.Net is hit and miss. Guess I’ll have to hope someone actually pays attention to this tomorrow. Back to uninstalling and reinstalling till I can actually get this thing to work. Still no idea why Battle.net.exe sometimes has 4 or more icons in the Notification Area Icons box near the Clock on my Desktop.

It’s either that or I have to do a Factory Reset which is just ‘great’.

Howdy Lacryma,

This definitely seems strange but we aren’t aware of any widespread reports similar to what you described, so this doesn’t seem to be something specific with the Blizzard app or any recent update. The error you described appears to be coming from Windows and may indicate a deeper problem even if the Blizzard app suddenly started working. From what I can tell, these errors happen due to drive allocation letters and/or USB peripherals, which would be outside our ability to help with. You may want to disconnect any unnecessary devices or drives and retest. Testing a new Windows user account may also be worth a shot.

I have done a complete factory reset As in I went through the entire PC recycle method. and the issue is still occurring. Now battle net is asking me for a connection to D drive which my computer does not have. At this point I have no idea what other options are on the table for me.

7

I would have thought that doing a total factory reset would solve this problem, the fact that it doesn’t once again reinforces to me that this has to be an issue with Blizzards software and whatever update you did yesterday.

Please advise.

I’m running into the same issue when launching the battlenet app on Windows 8.1 Pro

“Windows - No Disk
(X) Exception Processing Message 0xc0000013 - Unexpected parameters"
Cancel/Try Again/Skip yet it pops up again and again.

Running as admin doesn’t do anything. Task manager and ending the process is the only way to get the error to stop appearing. Also uninstalled and reinstalled.

You nailed it! That’s that’s exactly what I have too. Tell me after you were using task manager to shut down the inordinate number of battle net’s running in the little Box near the clock on the computer, did you enter in A state Where the Error screen kept popping up in perpetuity?

Also although I think I already know the answer, did you have any power fluctuations yesterday at around 2:30 to 3:00 p.m. in the afternoon?

-Seriously doubts the power outage caused this, due to the sheer number of protective measures and A/V that were installed to ensure Edison and other entities didn’t destroy another computer, after the incompetent slugs fried one during Mists of Pandaria.-

By this I mean did you Enter a State where every time you hit cancel try again or the other one it just made the popup Box pop up again and again and again and again?

Also apologies for the typos, I’m forced to use my phone to communicate on the forums now by virtue of I’m going through my 2nd full factory reset on my computer and it probably won’t recover until 10 o’clock tonight.

I am getting the exact same error as well.

After several hours spent doing a complete and total wipe of my PC, for the 2nd time I might add…

I am just about ready to try installing battle net again. I will let you guys know if the error continues. If it does there’s nothing more I can do I have literally exhausted the nuclear option twice.

I do not consider being asked to upgrade to windows 10, a solution. Rather I feel like blizzard should give us a rollback on the battle net app until they fix whatever is causing this issue.

Ok. So. I’ve gone through every step. I have done ‘everything’ including a full factory reset. Nothing works. The error however has changed now. It still denies me access to Battle.net in full.

Battle.net.exe - No Disk
(X) There is no disk in the drive. Please insert a disk into drive D:.

I. do. not. have. a. D. Drive. I have just done a full factory reset.

The Extensive One. The 9 hour kind.

Why is it asking for a non-existant drive? Rollback the B.Net App. This is comically stupid, and the fact that people were saying it was due to the power outtage was even more ridiculous, what is really going on and when can we expect a tangible resolution?

Beyond that, issue is identical as Brerae defined it. System goes into an infinite loop of error messages. Control Panel action to shut down the B.Net app is required to proceed.

I’ve been getting the same exact error since the latest Bnet app update! Now, attempting to launch the app results in:

“Exception Processing Message 0xc0000013 - Unexpected parameters”

Pressing “cancel” , “try again”, or “skip” doesn’t do anything, and the error window locks you into an endless loop. I finally had to kill the Bnet app process through task manager to stop it. Tried all the troubleshooting steps mentioned to no avail.

I have also be plagued with this error, and it happens for Overwatch or anything from Blizzard I try to launch. It was working fine for months, and then on Sept 3rd it doesn’t work. Restarting the PC doesn’t help. The Windows OS is otherwise healthy and it can run chrome, MS Teams, Outlook and anything else just fine. This is a Blizzard problem. Even after a login to the Battle Net screen, this error continues to pop up and one never gets to the actual application. In my case I only see 4 Battle.net.exe apps in task manager. I’m not sure what is normal there. I have to kill them manually in there.

To reproduce this issue, I suggest playing around with a system where a phone might be plugged in and unplugged, or having USB card reader and plugging in some media and then unplug. In my case the error is happening with no media connected. But I did have an SD card and phone connected prior to seeing the error. Right now, just C: drive running Windows 8.1 all patched. I have a disks D, E, F and G all showing no media and the error can be experienced. There is only one user account on my PC.

I haven’t been having this same error, but ever since the same patch you’re referring to, my Win10 machine simply will not start the Battle.net desktop app. (See my unanswered thread at Unable to run Blizzard desktop app).

Seems that patch really messed some things up.

17

I uninstalled Battle Net. Then ran Overwatch which triggered a reinstall. This completed okay and then it ran. I was able to run Overwatch, but did see more of the same No Disk -> “Exception Processing Message” errors. I quit Overwatch and Battle Net. On launching Overwatch again (which triggers Battle Net start) I am back to square one with the errors. I can see the Battle Net login after a dozen or so errors, and after logging in, the application never starts - it is an endless loop of these No Disk errors.

18

Yeah, to chime in with Reveranditus, I do use my PC to charge my phone via a USB. That being said I am at a loss as to why after 2 full factory resets with only the mouse and keyboard plugged in, it is still occurring. I would of thought a PC fresh and ready for recycle would not have this issue.

I went through all of the steps the GMs proscribed. My issue has ‘changed back’ as a result and I am at square 1 again, where I was before I wiped my PC. Posting the steps in the off-chance it helps someone else.

Hey there XXXXXXX,

Tech Specialist XXXXXXXX at your service :slight_smile: Reading over the incident it sounds like Battle.net was originally installed to a Drive that was removed from the computer. So we’ll want to clean some folders form the system and reinstall the app.

  1. Hold CTRL and press R
  2. In the box, type %ProgramData% then hit enter. This will open a folder on the computer.
  3. Delete Battle.net and Blizzard Entertainment folders. Note, if you receive any errors with this process please restart the computer then retry. Closing any running Battle.net tasks in Task Manager may also work.
  4. Attempt a new installation via this link: https://www.blizzard.com/en-us/download/

Note, please use the default install path instead of any custom file path.

If it’s still not working after that please provide us with updated system files so we can verify any new error reporting after these changes were made: https://battle.net/support/article/000012988

I have sent the MSInfo and DXDiag as requested.

Here’s hoping things shake out for the better.

Hi Zenlaka,

Ever since I booted up Battle.net absolutely fine yesterday and it did an update and asked me to restart battle.net, I am having the exact same problem as OP. Down to the details.

I also have Windows 8.1

I currently cannot log in and have made threads about this also.

I have the exact same problem since yesterday,

down to the infinitely repeating No Disk error asking for drive D:, which I don’t have. Exactly the same. I also have Windows 8.1 (not Pro) x64.

Everything else works absolutely fine on my computer and I have changed nothing at all for a very long time except the Battle.net update it did when I logged in yesterday. Immediately after the update it started doing this.
