Download of WindowsDeveloperPreview-64bit-English-Developer.iso repeatedly failing

    Question

  • Hi,

    I'm trying to download the Windows 8 Developer Preview with developer tools English 64-bit iso here in the UK and it keeps failing about 98% through. Attempting to resume the download fails too.

    Any thoughts?

    Cheers, Ian.

  • If you're using a browser to download it, try using a download manager instead. They can be more reliable with large files.

    Free Download Manager is a popular one:
    http://www.freedownloadmanager.org/

     

     

    You should not install Windows 8 Developer Preview on your main computer - it's not even a beta product yet and bugs are to be expected.

    From the main download page:

    The Windows Developer Preview is a pre-beta version of Windows 8 for developers. These downloads include prerelease software that may change without notice. The software is provided as is, and you bear the risk of using it. It may not be stable, operate correctly or work the way the final version of the software will. It should not be used in a production environment.

    Also, it is stated on the Windows Developer Preview download page that you must reinstall the previous OS:

    Notes about installing the Windows Developer Preview
    You can't uninstall the Windows Developer Preview. To reinstall your previous operating system, you must have restore or installation media.

  • Hi IanLyon,

    also, please check if your network service has a download limit.

  • Thanks for the ideas guys.

    I'm not aware of any download limit on my service. I've downloaded large files before without problem.

    Re the download manager thing, I'm used to using one when I d/l from MS volume licensing but that's because it offers to install itself automatically. I've not tried using a '3rd party' offering before (ie one that I had to go looking for).

    I've tried this d/l with IE8 and IE9 (on two different machines) with exactly the same result. I'm going to try it again now on a third machine which is at a different site with a different ISP. If that fails I'll try the d/l manager route.

    Cheers, Ian.

  • Hello Ian,

    From where are you attempting to download the Windows Developer Preview?

    Use the location here to be sure you are downloading the correct ISO.

    http://msdn.microsoft.com/en-us/windows/apps/br229516

    Verify the burn and the Sha 1 Hash. For the Windows Developer Preview 64-bit with tools, the Sha 1 hash is:
    Sha 1 hash - 6FE9352FB59F6D0789AF35D1001BD4E4E81E42AF
    The download size is 4.8 GB.

    Let us know if this helps.

  • Hi Marilyn,

    Thanks for getting back.

    I have been attempting to download the ISO from the same location as your link.

    I downloaded the 32-bit version without problem, but I need to see the developer tools.

    Forgive my ignorance but I thought the Sha1 hash was something I would use to check the file once I'd downloaded it. I haven't managed to get that far.

    Cheers, Ian.

  • I thought the Sha1 hash was something I would use to check the file once I'd downloaded it. I haven't managed to get that far.

    If the download stops before it's complete you don't need to verify the hash since you know it didn't finish. When it does finish you should verify it to check for errors.

    If you've only tried downloading it with a web browser I would recommend a download manager. There are many available - you can use the one from my last post or find one that may have features you want.

  • Just in case try run disk clean up and free up some space in your PC and also try change download location.

    Also turn off your router for few minutes and turn it on again and start downloading.

  • Hi,

    Still getting nowhere with this. Have tried on a machine at work (different router - Cisco SR520) because wondered if might be bug in NAT implementation on my home router - no go - same problem.

    Latest attempt was to use 'wget' command line d/l tool. Gives the following:

  • Hello Ian,

    Can you download the 32-bit ISO without the developer tools?
    Give a try as I have seen issues with downloading the developer tools.

    This may give us a hint.

    Thanks,
    Marilyn

  • Hi Marilyn,

    Thanks for the speedy reply.

    Yes, as I said earlier in this thread, I downloaded the 32-bit (no devel tools) iso without problem.

    Win8 32-bit is up and running here on a Hyper-V VM and looking good!

    Cheers, Ian.

  • If the file is nearly complete but corrupt you can try using QUICKPAR to repair the missing/corrupt portions of the file. Install QUICKPAR on your computer (freeware) and then download each of these files into the same directory as your ISO. Then double-click on the PAR2 file (the first one) and QUICKPAR will validate the file and repair it as best it can. Not a guaranteed solution but it can help you avoid re-downloading 6 GB.

    Link to QUICKPAR: http://www.quickpar.org.uk/

  • Hi Ben,

    Thanks for the suggestion, and for the files. Tried that but no go I'm afraid. Here's a screen-shot of the QuickPar output.

    Cheers, Ian.

  • Looks like your file is about 6% corrupt/missing. The parity volumes I posted before weren't enough for your particular file. Here are new PAR2 files that will hopefully work (download only as many as you need, starting at the top)

    Here are the direct links:

  • Hi Ben,

    Thanks for continuing to look at this one for me. I've tried to access the skydrive link but am getting: "There's a temporary problem with the service. Please try again. If you continue to get this message, try again later."

    I will 'try again later' but, in the meantime, can you help me to understand why we're needing to go through this rather strange and convoluted process?

    I've been exchanging quite a few e-mails with my ISP over this. They've tried downloading the file a few times (onto a CentOS 5.7 box) and not had problems.

    I've run into similar problems trying to d/l this file onto two Win Svr 2k8R2 boxes and one (32-bit) Win Svr 2k3 box. One of the 2k8 machines is connected via a Cisco router, the other via a Draytek, in both cases using NAT. I tried the box connected via the Cisco because my ISP raised the spectre that this could be a bug in the router's NAT implementation. The fact that the two different makes of router seem to produce a very similar outcome would appear to dispel that.

    So I'm stumped and so is my ISP. Have you got any ideas?

    Cheers, Ian.

  • I suspect you got a partially downloaded file. This can happen sometimes with noisy internet connections (think downloading a file on a dial-up connection and someone else picks up the phone, but doesn't corrupt the transmission enough to totally disconnect the internet connection). Using a download manager to "resume" the transfer might work, but there might be corrupt bits in between where the transfer got cut off and resumed. That's where par2 is most useful.

    However, with enough recovery blocks, par2 can also fix a partially downloaded file. These recovery blocks should be able to fix between 6-7% of the file.

    I'll put the par2 files on my normal server again. Start with the top 2 and work your way down until you have enough blocks. I will try to keep these files available until Windows 8 Beta ships. Here are the direct links:

  • Hi Ben,

    Many thanks for the new links. I will try to patch up my download as you suggest.

    Yes, I did get a 'partially downloaded file'. But I've tried 4 or 5 times, over two different DSL lines, always with the result that the download aborts around 90% through and neither IE9 or wget can 'resume' it (at all).

    This is not a noisy connection. There's something systemically wrong. Any ideas what?

    Cheers, Ian.

  • You're not the first one who had an issue downloading the Windows Developer Preview. I am asking around internally to see if there is anything we can do to enhance the download experience for the upcoming Beta release.

    Note: If you have a MSDN or TechNet subscription, you can also download the WDP from Subscriber Downloads using the Microsoft Download Manager, which offers a more robust download experience.

    P.S. Please let me know if the par2 files worked for you!

  • Hi Ben,

    Many thanks for the extra links. In the end, rather than trying to patch up my incomplete download, which felt a bit desperate, what I did was to fire up a Hyper-V VM with the CentOS 6.2 OS and download the file from within the VM. Downloading using CentOS had worked for the tech support guy at my ISP so I thought it might for me to. And indeed it did.

    Unless something has changed your end I have then to suspect that the problems I was having were something to do with the Windows operating systems and/or software I was using (tried Svr 2k3 and 2k8R2, using IE8, IE9 and wget).

    Output from 'wget' and 'sha1sum' on CentOS terminal shown below.

    Incidentally, installing CentOS involved downloading a 4.3GB iso (from an ftp server) which I did from within Svr 2k8R2 using wget without problem. All very strange!

    Thanks again for all of your help - much appreciated.

    Cheers, Ian.
