    Having exactly the same issue - tried that twice and still comes up with an error after hanging on 'Preparing for install'...

    Same here. I've tried the "delete and force install" solution twice now and both times it has downloaded in Windows Update, only to fail installation.

    I seriously doubt it will ever work for me. Guess I'll try an ISO.

    Any updates on this error? Im stuck at this step as well... have forced the update twice both with the same error after it finishes downloading. It starts installing but after a while it just shows the red 80240020 error. I now reboted my pc and am trying for the third time now, hope it works this time x)

    First download was about 5gb, second was 8gb, this third one is almost 3gb... whats the deal here?

    What this error means is, your Windows 10 installation folder is unfinished and/or corrupted. Now, how do you fix that?
    1. Go into "C:\Windows\SoftwareDistribution\Download" and delete everything in that folder.
    2. Now, run the command prompt as an administrator. Type in "wuauclt.exe /updatenow".
    3. Go to your Control Panel > Windows Update and your Windows 10 should start re-downloading from scratch, hopefully without flaws this time.

    I found a solution:

    go to C:/windows/softwaredistribution/download and delete everything in this folder

    After doing that try to run CMD again (as admin) and write in the wuauclt.exe/updatenow

    Now you should just watch it to start downloading in the win update without crashing. Hope it works for everybody, worked for me.

    I have done this three times now. After the third one i emptied the download folder again and rebooted my pc instead, i then executed the command /updatenow in cmd as admin after logging in... Is downloading again right now for the 4th time, i sure hope it works this time, or at least soon!!!

    How is it a time zone error? This is the 29th I am in Calif and it is 8:47 when are they going to let it go. When I clear the folder it gives me a message something needs your attention before installing windows 10 click check pc button and it just goes back to update and does nothing.

    Same issue have tried the fix half a dozen times and it seems the download size varies each time.

    You can also use this link:

    Windows 10

    But keep in mind it is a FRESH install and you will need your Win 7/8 product key to install and you will lose other features (MS free DVD player) by not upgrading.

    What I did I opened Win10 App (which is beside the clock) and it updated the system for me. I did it at 2AM Pacific time (5PM local time July 29).

    I kept getting the same error, eventually I downloaded the MediaCreationToolx64 from MS's website and used that to create an installation usb-stick... which worked out nicely.
    You can also use the tool to create a DVD instead, if you prefer that.

    I just had word from Microsoft that they're actively investigating this issue. I'll respond if/when I get further news. I know this is frustrating, its affecting me as well.

    Huh. My last attempt worked. I deleted the SoftwareDistribution folder and used the wuauclt.exe method. This time the download was over 5Gb where before it was about 3. I guess the update package has been fixed on the server for some users.

    Same problem here since this morning. Have tried the SoftwareDistribution fix, no joy.

    Windows Update tells that I need to check my PC before upgrading and "Before installing Windows 10 Preview, Something Needs Your Attention." The pane to the right indicates 0 kb. Clicking on the "Check Your PC" button just loops me back to the Update screen.

    So far, having no fun.

    Been there, tried installing all other updates before using the command prompt. Then it started downloading.
    Downloaded a 5GB package at first, setup.exe told me that boot.wim was missing, cleared the SoftwareDistribution/Download folder, redid the command prompt and currently downloading a 8GB package. Making a USB from the MCT in case it fails again.

    First time failed for me too on desktop using the win media thing; the desktop on the other hand went rather smooth but still has an AMD Radeon HD 5000 series issue along with the ATI Mobiliy gfx card.

    It failed on both my desktop and my Surface Pro 2. I redownloaded the update multiple times on both machines but still no luck.
