Click here to turn on just Defender shows the arrow goes around and around. It's protection against the virus only ever on this computer. a scan is a non technical question before the update. Is there a way cable to turn Defender? Pete

  • My Windows Defender will not remain, it turns off

    original title: My Windows Defender

    My Windows Defender will not stay on, even though I have a scan scheduled @ 02:00 every day. I do not understand why the Defender stops, and I get a warning telling me it's off. It analyzes every day @ 02:00, and I manually do a quick scan when I see the warning icon. Help!
    Thank you for your help.

    Copy davidhk129 answer to the question of Windows Defender won't start do not:

    Here's a direct copy...

    If you have
    one of the following AV, antivirus, programs installed, it will stop your Windows Defender. Purpose of these AVs have their own advocates. 2 defenders on the same machine will create conflicts.
    Bottom line: it's ok.
    It's normal.
    List of AVs which will stop Windows Defender:

    Norton
    McAfee
    AVG
    Microsoft Security
    Essentials

    If you don't have AV programs above, here's how to restart Windows Defender:

    Start button > in the search box, type Services > press the Enter key > scroll to find Windows Defender, click on it >...
    topic status , it must be said... Has begun
    under Startup Type, it must be said... Automatic
    If it does not say that, right click on Windows
    Defender > click Properties >
    in Startup Type, click on the pointer to the right and select automatic
    to the service status, click Start
    Click OK when finished.

  • Windows Defender will not work

    To activate... check the box opposite.
    To disable, uncheck the box in front. For the benefits of others looking for answers, please mark as answer suggestion if it solves your problem.

    I hope someone can help please!
    I downloaded the demo of dreamweaver 8 yesterday and I installed and ran fine. Today, that he will not run in front of the start screen. He stands up and asks if I want to buy or wear on the trial--I take trials and the dreamweaver start screen 8 arrives, and then nothing happens. The program does not start. I uninstalled and reinstalled. I rebooted etc - still no go. The other trial, I downloaded (firestarter) works very well yet.

    Yes - it ran fine yesterday.
    I think I found the answer. I searched through the posts here & found someone else with the same question a few months ago.

  • Apple iTunes will not run.

    Apple iTunes will not run.  I reinstalled several times. The error message has something to do with DEP.  But I doubt that iTunes referred to system memory.  In addition, my PC has hardware DEP, no software.

    Thank you.  Found the answer in the Apple community.  I had to reinstall Quicktime in order to get iTunes to run.  They had lost their association.  Everything works now.

    Hi John Hurst,

    Currently, Acrobat DC is fully compatible with Office 2013. About compatibility with Office 2016, our engineering team work and it should be included in future updates (quarterly updates) of Acrobat DC and not another version.

    In addition, as a workaround, you can use PDF in Office 2016 printer or open the document directly in Adobe Acrobat DC to convert the document to PDF format.

  • End action will not run due to the action of late about final chapter

    I'm still doing my first project, and I get this error message: end action will not run because of the end about final chapter action.

    My calendar:

    I have a unique calendar consisting of a couple of reviews. There is a "chapter Starting Point" yet and 3 additional Points of chapter, I added.

    My goal:

    • A main Menu with
      • A 'Play' button that simply plays the entire timeline, beginning to end, and when finished go back to the main Menu.
      • A 'Scènes' button which brings up a submenu
    • A submenu with 4 buttons of chapter, which each would play a chapter in the timeline and return to the same/auto submenu when finished.

    My end Actions:

    It seems that the end Action is necessary for what is defined. Thus,.

    • The Action of 'end' of the timeline is to return to the main Menu.
    • The Action of 'end' for each chapter in the timeline must return to the submenu.

    My flowchart

    • First thing that works is the main Menu.
      • Links Play button of the timeline (which the end action is back to the main menu).
      • The scenes in the submenu button links
    • In the submenu, each chapter button links to the chapter Point suitable in the timeline (each chapter has an end action to return to the submenu).

    All of this makes perfect sense to me and it reflects exactly what I want to do. If clearly, it won't work!

    When I check my project, I get the error mentioned above. I do not understand how it is even possible to avoid this error: your timeline MUST have an end action, your timeline must have at least a chapter point and each chapter MUST have an end action.

    Thus, by definition, it seems that still

    • REQUIRES the timeline for action to end,
    • REQUIRES the last chapter on the timeline to have an end action, and
    • Gives you an error when you do what it takes.

    What the...?

    My solution

    I was finally able to work around the problem by creating a playlist of "chapter" for each chapter, that is, I created a "Chapter 1 Playlist" where the content has been a link to the chapter Point 1, a "Chapter 2 Playlist" where the content has been a link to Chapter 2 Point, etc.

    Then in my submenu, instead of linking to a Chapter Point, I've linked to a list of reading chapter instead and in each Chapter Playlist I put an end to "return to the submenu" action

    It worked - but it really seems kludgy and I can't help but shake the feeling that I do something wrong or I'm doing something good?

    Your "Workaround" is the current main method. Chapter Playlists are a "function". Yes, it seems kludgy, but it avoids the use of substitutions, which are necessary for your first method and cause many headaches without end users.

    Chapters DO NOT need action to end and your workaround solution, should not have their.

    Main timeline, end to the main menu action.

    Chapter playlists, end to the submenu action.

    No further action at the end of editing/chapter.
