I keep getting failed when you try to download the required update just get error 66A

I tried questions from what I can understand, but still get failed whenever I try to download this critical update.

66A error keeps appearing every time.

Hi doors,

1. who is the essential update that fails to install?

2. is the problem isolated to any particular update?

3. what operating system is installed on the computer?

Try the following steps:

Step 1:

Temporarily disable the antivirus software and check if it helps:

Caution:
Antivirus software can help protect your computer against viruses and other security threats. In most cases, you should not disable your antivirus software. If you do not disable temporarily to install other software, you must reactivate as soon as you are finished. If you are connected to the Internet or a network during the time that your antivirus software is disabled, your computer is vulnerable to attacks.

Step 2:

Reset Windows components updates default and check to see if it helps:

I hope this helps.

    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.

  • Fail when you try to play the folio of the Adobe account

    Hello!

    When I try to download the new file on the iPad, with the Adobe Content Viewer.

    I got a message telling me that a file is missing or is not valid (in Swedish).

    I clicked "Refresh" in the viewer generator, and the version comes from Adobes tutorial assets 2.

    BR

    This problem is caused by the fact that the new Adobe Content Viewer is not yet available on the App Store, so that you try to open a newer folio with an older Viewer. If you have access to the web client Folio producer (digitalpublishing.acrobat.com), you can "publish" app, which moves the folio in an area that can be displayed by the Adobe Content Viewer. Or, you can wait a few days until the Viewer is updated.

  • Error when you try to download the application forms, not a valid Windows 32

    not a win32 application invalid and stop the download

    When I try to download tax forms IRS my computer says "application not valid windows 32 and stops downloading just 15 seconds before its filled! What the heck is wrong?

    Hello shelleyjane,

    Get the error: not a valid 32-bit application can have several origins:
    I have listed some of them below, and possible solutions.

    The file is corrupted, bad or missing.
    -If the hard disk is damaged or hurt it cause work programs to fail, either because not all data can be read from the hard drive the program is damaged on the drive. Run scandisk and defrag on the hard disk to check for potential errors.
    -If you run the program from a shortcut on the computer, verify that the program is still on the computer. In some cases if the program is no longer installed on the computer, you can get this error.
    -You can download the app again and see if you still get the error message.

    File is not designed for your version of Windows:
    -If you try to run a program that is not designed for your version of Windows, you can get this error.
    -Although many old programs designed to work in older versions of Windows will work with new versions of Windows, unfortunately, not all programs will not work.
    -If the program is an MS-DOS program more former start program or Windows, you can get this error.
    -If the program is designed for a 64-bit version of Windows and you are running in a 32-bit version of Windows, it will not work and generate this error.

    File is a virus, worm or other malicious program file.
    -
    This error can be generated by a file that is a virus, worm, Trojan horse or other type of malware file. Often, this will result because the antivirus installed on the computer will not allow the file to install or run. Try to analyze the file to check, it is not a virus or infected.
    -If the file has been checked and is clean, it is always possible that the virus protection program or a another program installed on the computer is at the origin of questions during installation or execution of the program. Start the computer in Mode safe and try to run the program. start the computer in Mode safe will be that nothing is running in the background that could cause this problem.

    Hardware incompatibility.

    -If you get this error during the installation of a program, it is also possible that the CD-ROM drive or the drive that you are installing the program from is not compatible with Windows or has drivers that are not compatible with Windows.
    -Download the latest drivers for your CD player or other of the manufacturer of the computer or the manufacturer of the equipment. (Microsoft does not pilot for other materials)

    How to remove an update for Windows Vista

    If the fix works, I recommend that you 'hide' it so that it not be reinstalled automatically.

    Instructions below:

    If you don't want Windows to install an update, you need to hide.

    1. Open Windows Update by clicking on the button start . In the search box, type Update, and then in the list of results, click Windows Update.

    2. In the left pane, click Find updates.

    3. When Windows finds updates for your computer, do one of the following:

      • Click the link that tells you important updates are available if you have some updates to hide.

      • Click the link that tells you optional updates are available if you have optional updates to hide.

    4. Do right click the update you want to install, and then click Hide update. The next time you check the updates, the update will not be automatically selected or installed. If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.
