    Windows 8.1 update won't download. Error code 0x80240031


    I looked up this error code and it says "file is not the right format"

    What "file is not the right format?" I get the update button, and after I click to download it gives me this error. Anyway I tried multiple times...no joy...same error code. The version of Windows 8.0 Pro that I am running was an upgrade from windows 7.0. And my Windows 8.0 appears to be working fine otherwise. Anyone know how can I fix this error, and get the 8.1 update?

    Since you seem to be on a leading edge of reporting this issue, I can only assume that you are the first to encounter such an error; however, if you have some idle time waiting for a "me to" response, you might want to make sure you have applied all Windows Updates to current and if you are already there, you can try this if you like:

    Open an elevated command prompt and type/run: "sfc /scannow" (without quotes).

    If errors or discrepancies are reported, run this second command in the same open window:

    Dism /Online /Cleanup-Image /RestoreHealth

    Once done, try your update again and see what happens. Here is the entire tutorial for your reference:

    Good luck.

    Thank you my2cents. I just ran SFC /SCANNOW and there are no integrity problems. I also checked for updates and I have only 2 recommended and no important updates. Rebooted and ran a registry scan with ccleaner. Tried to download again and got same error code 0x80240031. I guess I just have to be patient and see if anyone else encounters the same problem.

    Is one of those recommended updates KB 2871839? If so, install it. Also, I just looked at your specs and I noticed this notation:

    OS Windows 8 Pro,7 Ultimate & Ubuntu 12.10

    So, is there any dual boot arrangement here? If so, that might cause an issue...

    My two recommended updates are Bing Desktop and Bing Bar. And I don't use a boot menu. All 3 of my operating systems are on their own SSD removable drive. I only have one active drive plugged in at a time.

    Just thought of something. I am using the Classic Shell Start Menu by ivosoft on my Windows 8.0. Could that be the problem?

    I doubt it but you have to start somewhere so give it an uninstall and see what happens. If that doesn't work, you could also try this repair install without losing too much. Maybe that will correct your current issue. Good luck.

    I have the EXACT same error and have been battling it for the last 3 hours trying to figure it out. I did some searches and I thought the issue was related to the language that is setup, but I've followed every fix and I find and I still get the same error after the download gets to 2/3. I'm completely lost as to how and fix this.

    I'm pretty sure I know what the problem is. It's my ISP Verizon 4G LTE. They must be blocking it for some reason.

    I just got the exact same error on my laptop as I got on my desktop computer. Using the same LAN.

    If anyone else is getting this update error using wireless Verizon 4G LTE, please let me know. That will confirm my suspicions.

    I'm using Time Warner Cable as my ISP and I'm still getting the same error. It can't be the ISP I wouldn't think.
