    Hi julieWI,

    Please use the Forum of the community for Vista.

    When you say you tried manual installation, do you mean you went to MS and downloaded the update and tried to install it like that?

    If this isn't what you were doing, I recommend that download you and try this way.

    Because you have tried all the steps of troubleshooting and still faces questions, I suggest you do an InPlace upgrade using the Installation of Windows Vista disc.

    Note Run a repair installation will not damage files and applications that are currently installed on your computer. However, before you perform an Inplace upgrade, you can take a backup of important data. In case of a worst case scenario, you may have to reinstall all the programs. Make sure that you back up personal data to disks or other external storage devices before performing an upgrade on the spot. To perform an upgrade in-place, follow these steps.
    a. close all running applications.

    b. Insert the Windows Vista DVD into the DVD drive of the computer.

    c. in the settings window, click install now.

     

    Note If Windows does not automatically detect the DVD, follow these steps:

    Click on start and type Drive: \setup.exe in the box to start the search.

    Note The placeholder drive is the drive letter of the computer's DVD.

    List programs, click Setup.exe.

    In the settings window, click install now.

    a. click go online to get the latest updates for installation (recommended).

    b. type the CD key if you are prompted to do so.

    c. in the "Windows Installer" page select the operating system you want to update or Inplace.

    d. click Yes to accept the Microsoft software license agreement.

  • When you try to install the Vista SP1, getting error 800F0900 Code

    I'm unable to install service pack 1 for Windows Vista. It will go almost to the end of the installation, and then the error pops up.

    I installed system update readiness tool.

    I have rebooted background intel transfer serv, cryptograph serv and windows update.

    I tried going through windows update, but would not yet spent 0% of the dl. So I tried a few Fixer windows update and still the same thing.

    I've done the cmd as administrator and did the sfc/scannow, and he says there are errors that it is impossible to repair.

    I tried to make the findstr/c: "[SR]" windir\logs\cbs\cbs.log>sfcdetails.txt and retrieve a FINDSTR: cannot open windir\log\cbs\cbs.log.

    Then I tried c:\logs\cbs\cbs.log Notepad and get back that the system can't find the path specified.

    My laptop came with Vista on it so unfortunately I have no disk to work with.

    I have no answer why you cannot install SP1.

    My answer is on your trying to open the CBS.
    You have not correctly the command line.
    It's... notebook C:\windows\logs\cbs\cbs.log
    Copy and paste the command line instead of typing.
