    a. open system by clicking the Start button, clicking Control Panel, clicking system and Maintenance, and then click System.

    b. click on advanced system settings.  If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.

  • no solution does not work when you try to download itunes 10, I'm at my wits end. What can we do?

    I have everything all except unistall Windows Vista, is there something else I can do?

    You could try and uninstall all references to iTunes on your computer.

    Use the control panel to uninstall iTunes and software components in the following order:

    1. iTunes
    2. QuickTime
    3. Apple Software Update
    4. Apple Mobile Device Support
    5. Hello
    6. Application of Apple Support (iTunes 9 or later)

      Then a few solutions that worked is to install and erarlier version of iTunes as there have been some problems with version 10.

      If you work with Microsoft supports a call, it would be better to continue with this support.

      Otherwise, I would contact Apple for support of iTunes.

    Sincerely,

  • When you try to download a book from my library, I get the error message: error: check the activation.  What should I now please?

    When you try to download a book from my library, I get an error message: error, check activation.  What should I now please?

    Hi 7Philip1116,

    Using the Adobe Digital Editions software? If so, I suspect that you meet one of the known activation errors. Often, deactivation and reactivation (cmd-shift-D on Mac) or ctrl-shift-D Windows will solve the problem. Instructions step by step, but also other possible solutions are available here: Errors of Activation

    If it is not a question of Digital Editions or if the advice above do not resolve your problem, please respond with a few more details so that we can better solve the problems. What software Adobe are you use and the type of device/operating system? Can you provide a screenshot of the error? The specified item was not found.

    The work around works of Jean.  It would be nice if Adobe provided a real difficulty however.

    I have ADE installed 4.03.  The problem will occur as soon as that ADE is closed and reopened.    It takes so the patch every time allows you to download a book ADE.

    1. for Overdrive - select a book and click Download. -pop - up - select - Save file. - under the open with select - acsm_auto_file - download the file of social mobilization in your download directory.

    Repair Apple Software Update since the programs & features Panel configuration and then try again.

    For general advice, see troubleshooting problems with iTunes for Windows updates.

    The steps described in the second case are a guide to remove everything related to iTunes and then rebuild what is often a good starting point, unless the symptoms indicate a more specific approach.

    Review the other boxes and other support documents list to the bottom of the page, in case one of them applies.

    The more information box has direct links with the current and recent if you have problems to download, must revert to an older version or want to try the version of iTunes for Windows (64-bit - for older video cards) as a workaround for problems with installation or operation, or compatibility with third-party software.

    Backups of your library and device should be affected by these measures but there are links to backup and recovery advice there.

    Service Pack 2 offered by Windows (automatic) update yet?

    Windows Vista and Windows Server 2008 service Pack is not available for installation from Windows Update and automatic updates does not offer

    Cause
    This problem can occur for different reasons. However, the following reasons are the most common:

    • Already, you have the service pack installed and do not realize it.
    • You must install another update before you install the service pack.
    • You have not installed Service Pack 1 (SP1) and so you are not offered the option to install the Service Pack 2 (SP2). SP2 requires that you have installed SP1.
    • Components of the system that you must have to install the service pack are not installed on your computer.
    • You have a piece of hardware or software on your computer that is listed in the section "hardware and software which if present will result in Windows Update and automatic updates offers is not a service pack " article.
    • You have installed a preliminary version of a service pack, and it was not properly uninstalled before that you tried to install the final version of the service pack

    Service Pack 2 for Windows Vista and Windows Server 2008 is not available to users for which the following update is hidden:

    955430 description of the Windows Vista and Windows Server 2008 installation feature software update released April 28, 2009

    See article KB, Matt. When the system is ready for SP2 [as in you will be informed of the automatic update], suggest then you download the full SP2 package, save, temporarily disable AVG and then install SP2.
    The MS KB article below has sound advice for steps, you have to take before installing a Service Pack

    What you need to know before you install Service Pack 1

    Scan SFC enforcement procedure:

    2. on the Start Menu, click all programs followed by accessories

    3. in the menu accessories, right-click on command line option

    4. in the drop-down menu that appears, click the "Run as Administrator" option

    5. If you have the User Account Control (UAC) enabled, you will be asked permission before the opening of the command line. You simply press the button continue if you are the administrator or insert password etc.

    6. in the command prompt window, type: sfc/scannow then press enter

    7. a message is displayed to indicate that "the analysis of the system will start.

    8. be patient because the analysis may take some time

    9. If all files must be replaced, SFC will replace them. You may be asked to insert your DVD of Windows Vista/Windows 7 for this process to continue

    10. If all goes although you should, after the analysis, see the following message "Windows resource protection not found any breach of integrity.

    11. once the scan is finished, close the command prompt window, restart the computer and check.

    Also have a related problem about MS Maliciouws software removal tool. For download, but read in the KB that: in XP, the vacuum cleaner will remove the malware, but doing so may trigger the File Protection Win with damages to my operating system.  the tool will attempt to repair the damage, but to rehabilitate prior to infection, that I need to insert the CD of Win. As my computer came with Windows preinstalled, I do not have a disk and will not take the risk of damage, that I can't fix. Do I not download or not... ? Another solution... ?  I also fear that this tool could settle into the routine Win Update and need guidance on the prevention of this facility, if possible, or what to do if it cannot be prevented.
