Why can I not install Windows 7 on my computer?

anilzedia March 6, 2011

My motherboard is 845 Intel and I’m using Windows XP. I cannot install Windows 7 in my computer. Why?

When I install Windows 7 I get errorcode:0x80070001. What is this and why can’t I use Windows 7? Help me!

      so you're saying that installing Windows 7 is slow? Do you install it often? Why? What happens after you installed it? Is the speed using Windows 7 ok?

      It sounds like a very particular problem and I would suggest that you submit a new question. But first check out the Windows on Speed guide. Good luck!

    Please try the following:

    Click Start >> Run >>
    Type the follow command in the Open box.
    "regsvr32 wuapi.dll" (w/o quotes)
    Press Ok
    Type "regsvr32 wups.dll" (w/o quotes)
    Press Ok
    Type "regsvr32 wuaueng.dll" (w/o quotes)
    Press Ok
    Type "regsvr32 wucltui.dll" (w/o quotes)
    Press Ok
    Type "regsvr32 MSXML3.dll" (w/o quotes)
    Press Ok
    Type "regsvr32 atl.dll" (w/o quotes)
    Press Ok

    Now try the WU site again.

    If the above did not fix it:

    Rename (or just delete) the SoftwareDistribution folder and
    see if it helps.

    You can use the procedure described here:


    Note that a side effect of renaming or deleting the SoftwareDistribution
    folder is that you lose your WU v5 History listing (not critical).

    (later on, you can just delete the renamed SoftwareDistribution

    Instead of following the procedure above to rename the
    SoftwareDistribution folder, you can delete it running the
    commands below in a command prompt (Start/Run --> cmd.exe)

    net.exe stop wuauserv
    rd /s /q %windir%softwaredistribution
    net.exe start wuauserv

    You are receiving this error because Setup is unable to validate the Windows image file; it believes it to be corrupt. So extract and brun again with imgburn.

    DID you checked your internet connection, disabkle any firewall.
    Go into your bios and make sure the 3 1/2 inch floppy disks are set to "none", and that will improve the speed of the setup starting

    otherway to instal

    Extract the iso to a folder using winrar
    copied the contents of the folder to the empty flash drive and put it in the pc.

    its also possible that your windows copy is exhausted?

    before instal clean your pc and registry.

    Are you chosing upgrade or clean instal with formating windows xp.
    VSS: Volume Shadow Copy Service warning: ASR writer Error 0x80070001

    Verifyyour ram and check if you can upgrade to 7:Windows 7 Upgrade Advisor

    1. Disable any security software before attempting to upgrade or do a clean install.
    2. Make sure your computer is updated (devices and applications)
    3. Disconnect any external devices before installing.
    4. Check your hard disk for any errors:
    Click Start
    Type: CMD, from the results, right click CMD
    Click 'Run as Administrator'
    At the Command Prompt, type: chkdsk /r
    When you restart your system, your computer will be scanned for errors and attempts will be made to correct them.

    install Vista or Windows 7using the "flat installation" technique described in KB928902.

    how are you trying to install Windows 7? Do you install from a self-burned DVD or an external drive? The error means that Setup is unable to validate the Windows image file and believes it is corrupt.

    Maybe there is an error on your DVD. Try to burn a new high quality DVD at the slowest speed possible. If this doesn't work, try to create a bootable USB flash drive instead. Check the following source for instructions on how to create the bootable flash drive. [Source]

    Also try to not reformat the hard drive when you attempt to install Windows 7.
